'Katy Perry: Part of Me': If you see only one 3-D concert film this summer ... ★★½

Paramount Pictures does not lie: The chipper, no-warts-and-all tour chronicle "Katy Perry: Part of Me" is indeed the 3-D movie music event of the summer. The only one, I believe. Unless Christopher Nolan's"The Dark Knight Rises" turns out to be in 3-D, featuring duets sung by men in peculiar facial accessories.
