[20] Sify wrote, "Kanchana 2 is no different from Lawrence's earlier horror comedies...The formula is the same – mix crass comedy with lots of horror, dead person's spirit getting into hero/heroine body, slapstick humour, glamour, melodrama, ladies sentiments, fight scenes...Add five songs, haunted house, scream and wailing sounds, it works".

[21] Indo-Asian News Service gave 2.5 stars out of 5 and wrote, "The movie, which follows a very clichéd and dated format of horror template, suffers heavily due to the lack of a good story" and called it "undoubtedly a weak film in the franchise".
