 The song received critical acclaim. Warren Truitt of About.com complimented Swift's "chim [ing]" in the ballad. Heather Phares of Allmusic praised the track, calling it "the best song on Hannah Montana: The Movie". She complimented it for being "more genuine, more effortless, than any of [Cyrus'] or Hannah's tracks". James Berardinelli agreed, stating, "Arguably, the movie's biggest mistake is having Taylor Swift perform a song, since she can sing and the comparison is not flattering to the movie's star." Leah Greenblatt of Entertainment Weekly described "Crazier" as "a pretty, yearning ballad." Premiere magazine reviewer Olivia Putnal referred to Swift's performance one of the film's "high points". Peter Hartlaub of The San Francisco Chronicle believed that Swift's cameo was enjoyable, but also calls it a mistake on the part of the filmmakers, explaining "Swift is so talented that she makes Cyrus seem bland by comparison." Perry Seibert from TV Guide wrote, "when genuine teen star Taylor Swift shows up to perform [...] she demonstrates all the spontaneity and authenticity that Miley Cyrus lacks."
