Most of the songs featured in “Rock of Ages” made me change the channel whenever their music videos popped up on MTV.

“Rock of Ages” is a jukebox musical built around songs from 1980s heavy metal hair bands, with some Pat Benatar and Journey thrown in to make you scratch your head. While I would be more attuned to a musical featuring the works of Blondie, Devo, ABC and other new wave acts, I usually accept any invitation to wallow in ’80s trivia, even if that means listening to Twisted Sister’s greatest hits (both of them) again.

No, the songs aren’t the problem with “Rock of Ages.” Nearly everything else is.
