Critical response The series was highly acclaimed by critics and audiences as one of the best TVB dramas ever created, one of few Hong Kong drama series to have stood against the test of time and to have aged well. At the time, it was the highest-rated TVB drama of 2010, at a rating of 9.2 out of 10 on the Chinese website
Douban, surpassing the rating of 8.7 for
Rosy Business. As of 2021, after new interest in the series when a potential fourth instalment was announced, the rating rose to 9.3, tying with two other series,
The Greed of Man and
War of the Genders as one of the highest-rated Hong Kong dramas. Although
No Regrets has more elements of romance than
Rosy Business, the writers kept them to a minimal. This choice along with Sheren Tang and Wayne Lai's onscreen chemistry were highly praised as the undying and unspoken love between the main leads, Cheng Kau-Mui and Lau Sing, felt much stronger than a typical romance and was very well received while some believed there could have been more romantic elements. Some younger viewers questioned if the two characters' relationship was considered romantic or just a strong friendship. Tang and Lai responded that although there are romantic feelings between the characters, neither contemplated it due to the turbulent timing and their different statuses. This relationship between the characters, dubbed as SingKau (醒九) by netizens, continues to have an active dedicated fanbase. On the other hand, people felt that the romance between the second leads Fala Chen and Raymond Wong's characters was dry and draggy. One of the series’ few criticisms was Chen's character's death and funeral, as it was deemed too long taking up the first half of episode 31, which aired as part of the finale. Audiences felt that the finale was touching while some felt that it was too tragic for a TVB drama but still gave very positive reviews. The drama was praised for being 'fresh' and different from other significant dramas including
Rosy Business since the first series focused on internal family conflict, a common theme among TVB series.
No Regrets, however, featured additional themes including war, rivalry, righteousness, love for one's country and history which has not been seen before in Hong Kong dramas. Also, the style of directing, editing and even the music have gone way beyond the standard of Hong Kong dramas, with many people liking it to an epic movie. The acting skills of Tang, Lai, and Ngo Ka-nin were praised for being versatile and vastly different from their characters in the prequel
Rosy Business. Mak Cheung-ching was also given credit for playing such a hated character so convincingly that his catch-phrase "My name Leung Fei Fan will be written backwards!" became widely used. Many actors who were cast as Japanese soldiers in
No Regrets did not have a Japanese background, but persevered in learning and using Japanese to film their scenes without needing to be voice dubbed. Their professionalism won the praise of both viewers and the producer Lee himself. However, viewers found that the props and set used were incorrect and unconvincing for the 1930s and 1940s and did not bring out the chaotic times of that era, largely due to the lack of budget. For example, cars and trains from the wrong decades were used and some parts of the Japanese Army's uniforms such as shoes and guns were incorrect. Despite
No Regrets' high anticipation and more complex plot, it was said to have had an even lower budget than
Rosy Business. The drama's female lead, Tang, had also commented on the production investment.
Accolades The drama and cast received eleven
TVB Anniversary Award nominations, winning five of them. After winning the Best Actor and Best Actress awards for
Rosy Business, Wayne Lai and Sheren Tang successfully defended their titles based on their brilliant performance in this drama respectively. Lai became the second actor to win the Best Actor award consecutively after
Gallen Lo in 1997 and 1998, while Tang became the first actress in TVB to win the Best Actress award consecutively. Both of them became the first ever couple in TVB's history to win the awards consecutively based on the same drama franchise. In addition, the series also won
Best Supporting Actress for Fala Chen,
Best Supporting Actor for Mak Cheung-Ching, and
Most Improved Male Artiste for Raymond Wong Ho-yin. After sweeping the main acting awards in the 2010 TVB Anniversary Awards ceremony,
No Regrets was expected to take home the
Best Drama award. However, the award went to romantic comedy drama
''Can't Buy Me Love'' unexpectedly, to audible gasps and shocking everyone who was present including the presenter of the award, acclaimed film director
Johnnie To who said before opening the envelope, "It's probably that one. Even the clapping and cheering sounds different" (referring to the loud cheers from the audience when the nomination clip for
No Regrets aired) and was visibly shocked saying "What? It's not actually" after he opened the envelope. It was later revealed the series had lost by 1 vote from one of six voting shareholders, Tommy Leung, who had originally voted for
The Mysteries of Love before a second round of voting was called to which he changed his vote. This led viewers to theorize that the decision was likely due to
No Regrets' prequel
Rosy Business winning over ''Can't Buy Me Love'
s prequel Beyond the Realm of Conscience the year prior and No Regrets
having already swept the other major awards since the network has a regular habit of dividing awards, such as creating the My Favourite Character Award, which is often simply given to the actor and actress who did not win Best Actor and Best Actress. Complaints were lodged immediately after the ceremony ended to TVB directly and online, with many saying that No Regrets'' should have won because of its high ratings as well as critical acclaim and better plot. The result is largely considered one of the biggest snubs for the Best Drama Award. Meanwhile,
No Regrets also gained other awards and achievement, including winning all four
Mingpao Weekly awards for TV programmes for a second year in a row following
Rosy Business' sweep, the first Shanghai Television Festival nominations for a Hong Kong TV drama for Tang and Lai and two awards for Chen and Mak at the
Asian Television Awards.
Viewership The series debuted on 18 October 2010 Mondays to Fridays at 8:30 pm with the cast holding a special celebration dinner. The premiere averaged 32 points, 4 points higher than
Rosy Business' 28 points and peaked at 36 points. Average ratings continued to rise in the later weeks. The finale episode, which aired as a two-hour special on Sunday 28 November 2010, had over 3 million Hong Kong TV live viewers, over 40% of the population of Hong Kong in 2010 and resulted in an unprecedented zero share of ratings for rival
Asia Television, which was airing a gospel programme at the time. The finale was aired alongside the finale of sitcom
Some Day. TVB aired a special celebratory program before and after the finales under the name , conducting interviews and games with the cast from both series. Several shops and restaurants in Hong Kong were spotted closing early, posting signs citing returning home to watch the finale as its reason. Even though the drama peaked at 47 points, one of the highest for TVB dramas during that time, many had expected the drama to reach 50 points for the finale and a higher overall rating for the series. It is likely that the 8:30 time slot had an effect on the overall ratings as many people in Hong Kong do not return home from work until later, which is why dramas placed in the 9:30 time slots tend to have higher viewership ratings. This decision was originally in part due to
Gun Metal Grey, the other anniversary series airing at 9:30, being deemed too violent and mature for the earlier time slot. Also, the plot of the finale was leaked in multiple tabloid magazines weeks beforehand. In addition, streaming was just becoming popular, with TVB's online service MyTV releasing new episodes hours after live broadcast for the first time. The drama attracted an unprecedented additional 3,739,955 clicks within the following few days on MyTV, 5 times runner-up
Some Day, and the highest ever in MyTV record. Each episode attracted more than 1 to over 2 million clicks on average. It also received the best rating in the Guangzhou region, with 17.1 million viewers and 60% share of ratings; the runner-up at 1.57 million viewers, had 5% share of ratings. == Viewership ratings ==
