Rock of Ages
($35.99 Blu-ray, $28.98 DVD, Warner)
Adapted from the stupid-cute Broadway musical built around 1980s and early ’90s hard-rock hits, this vehicle hitches itself to a wafer-thin plot about wannabe musicians trying to make it in L.A. Hairspray director Adam Shankman does get some fun turns out of the cast—including Tom Cruise as an Axel Rose-esque burnout and Alec Baldwin and Russell Brand as a pair of closeted club managers—but a lot of the songs don’t sell their scenes. The theatrical release was a hot mess—good luck making it through the Blu-ray’s 136-minute-long extended edition. Extras include a documentary with real 1980s hitmakers, behind-the-scenes featurettes and a music video with Mary J. Blige, Constantine Maroulis and Julianne Hough.
