There's some footage from Bieber's 2010 concert tour. A bunch of old family videos. Some guest appearances by Boys II Men, Miley Cyrus, Jaden Smith and Ludacris. And it's in 3D. ... I've got nothing to add to that, so I'll just close out with a refrain from the inimitable Mr. Bieber himself: "And I'm like baby, baby, baby ohh. Like baby, baby, baby noo. Like baby, baby, baby ohh." 105 minutes G.
