DVD: Rock of Ages

You don't expect much from a musical built on a foundation of 1980s glam-metal anthems, but you do expect it to be fun.

Rock of Ages isn't.

It's set in a supposedly debauched LA club, and yet it's as antiseptic as a hospital canteen, with forgettable choreography and dull production design snuffing out any of the flair which the songs might once have had. All it has to recommend it is Tom Cruise's out-there cameo as a wasted Jim Morrison-Axl Rose hybrid.
