"Korra Alone" received critical acclaim for its handling of complex themes and heavy subject matter such as Korra's
post-traumatic stress disorder. Rick Stevenson of
Looper stated the episode is a "masterpiece" for its chronicle of the "ongoing process of recovery — a process of anger, frustration, guilt, acceptance, failure, triumph, and change.", while C. K. Anderson of
Loud and Clear Reviews wrote that "The importance of this storyline cannot be overstated, not just to Legend of Korra, but to children’s entertainment in general. Korra’s struggle with mental health and trauma and her ability to overcome it sends a vital message to young viewers that might be experiencing similar struggles." The episode also received praise for Korra's character development, with Kaci Ferrell from
Den of Geek writing "the writers have matured Korra and improved the way they write her that I thoroughly enjoyed an episode focusing entirely on her; if you’ll remember, a lot of us had major problems with not particularly liking Korra as a character and finding other characters more interesting than her. The fact that now in the fourth season I can watch this entire episode and honestly say it’s one of my favourites says a lot about how the quality of her writing has improved." Many consider the episode to be the best in the series, such as Rich Knight from
Cinema Blend who states that "'Korra Alone' is all about trauma and how some people deal with it. And sometimes, people can’t deal with it, especially when they close themselves off to other people. We learn that Korra has been physically and mentally suffering ever since her encounter with Zaheer, to the extent that she’s broken as not only the Avatar, but as a person, too. This is the deepest this show ever gets, and also probably the darkest." Oliver Sava of
The A.V. Club stated that the episode "details the Avatar’s three years of slow healing in one heart-wrenching character study, exploring the depths of her fear and self-doubt by pitting her against a familiar foe: herself." Max Nicholson of
IGN gave the episode a score of 10 out of 10, writing that "It's rare that a 22-minute episode of a show can tell an emotionally satisfying story all its own, but this week's The Legend of Korra was definitely one of those episodes." and "the storytelling came from an emotional place, freeing up the episode to really explore Korra's PTSD and the affect Zaheer had on her physical and spiritual self. Beautifully animated, wonderfully scored and dramatically poignant, "Korra Alone" easily ranks among the best episodes of the series." == Notes ==
