This 3-D romp had Miley Cyrus/Hannah Montana blasting her/their hit songs like ''See You Again'' at the crowd, enabling kids to bop their heads and throw their arms up in the air as if they actually attended the show — but without parents needing to worry about how they were going to (A) find the precious live-concert tickets; (B) afford the ridiculous prices for them; and (C) shuffle their giddy kids back home from the arena. Genius.
