You will walk out of the theater humming this movie’s songs. Because you already know them all!

All musicals are at least a little a bit cheesy. Some are just more flagrant about it. “Rock of Ages” brings on plenty of cheese and has fun with it. The music is better than anticipated and script is funnier than expected.

The story, set in 1987, has all the rock’n’roll cliché themes. Girl meets boy: Julianne Hough plays Sherrie who comes to LA to be a star. She meets Drew, played by Diego Boneta. Rock is the devil’s work: Catherine Zeta-Jones plays a Tipper Gore type who wants to rid the city of rock. Rock is here to stay: Alec Baldwin is a club owner, fighting to keep his place open. You’re never too old to rock’n’roll: Tom Cruise is Stacee Jaxx, an Axl Rose type who may or may not be over the hill.

The big question people are asking: Can Tom Cruise sing? Well, yes. His versions will never replace the originals heard on St. Louis classic rock radio, but they get the job done.

Supporting cast members include Russell Brand as a club employee and Malin Akerman as a Rolling Stone reporter who interviews Stacee Jaxx and gets up close and very personal with him. Singer Mary J. Blige adds authenticity to the cast and, presumably, a bit of African-American audience appeal. Paul Giamatti is particularly sleazy as Stacee Jaxx’s manager.

“Rock of Ages” has a good balance of hard-rockin’ songs (“Pour Some Sugar on Me,” “Hit Me With Your Best Shot”), soft-rockin’ songs (“Waiting For a Girl Like You,” “Can’t Fight This Feeling”) and medium-rockin’ songs (“Don’t Stop Believin’,” “We Built This City”).

This is a fun movie. Music, dancing, laughs, romance, sex—they’re all there. It’ll rock you. Like a hurricane. (Also on the soundtrack!)
