Ratings Camp Rock premiered on
Disney Channel in the United States on June 20, 2008, with 8.9 million viewers, being the second most viewed
Disney Channel Original Movie at the time, only behind
High School Musical 2 (2007). Its June 21 showing on
ABC had 3.47 million viewers, and its June 22 showing on
ABC Family had 3.73 million viewers, according to
Nielsen SoundScan. The DVD topped the national home video sales chart for the week ending August 24. The film's premiere in Canada became
Family Channel's second-most-watched film ever, also behind
High School Musical, with 848,000 viewers. According to
Billboard the film attracted an audience of 146 million viewers in 160 nations and 30 languages.
Metacritic, which uses a
weighted average, assigned the film a score of 64 out of 100, based on 16 critics, indicating "generally favorable" reviews. Brian Lowry of
Variety stated that "it's difficult not to grudgingly admire the marketing savvy with which
Camp Rock was assembled".
New York Post critic Austin Smith called it a "really great movie, like a modern-day version of an old
Judy Garland-
Mickey Rooney picture" in which the kids "put on a show that improves the lives of all who see it". Barry Garron of
The Hollywood Reporter admired
Matthew Diamond's "solid enough" direction and
Demi Lovato's performance. He also said that with
Camp Rock, "Disney plucks another fresh face off its deep bench of young talent". Robert Lloyd of
Los Angeles Times wrote that the film "isn't particularly good, but it's good at what it does", and called it "inauthentic".
USA Todays Robert Blanco called the film "simultaneously overdone and underproduced" and said that "it jerks its way from point to point without bothering to explain the characters' behavior or inject any life into its musical numbers".
Entertainment Weeklys Gillian Flynn said "the strange and objectionable thing about the film's morality tale is that no one makes an outright decision to be brave or better", and called it "so rigidly formulated and unremarkable" that by the time the cast sings its finale,
We Rock, "it's hard to agree". Following the critics' line of comparison to
High School Musical, Jennifer Frey of
The Washington Post said that
Camp Rocks music is "in the same easy-to-memorize, dance-inspiring mode" as that of the previous franchise, "but not as catchy".
Daily Newss David Hinckley agreed, saying that "the songs don't feel as fresh" and "the film is specifically designed to ride on the success of the previous one", but he praised its formula that "goes back to the animated Disney classics of decades past", and called it "catchy and fun, a rock-steady Disney hit". Hinckley also praised the talent and performance of leads Joe Jonas and Lovato. In 2016,
Billboards Maria Sherman named
Camp Rock Lovato's best film to date, describing it as "something of a coming of age tale, one not only about believing in yourself, but accepting yourself".
USA Today added
Camp Rock to the top ten best summer camp movies of all time. Rebecca Alter of
Vulture ranked the film as one of the best Disney Channel Original Movies of all time. ==Sequel and spin-off==
