In walks the naive heroine from Iowa, Aguilera's Ali Rose.
She's hooked the minute she sees Cher's Tess, the club's co-owner and resident diva, belt out "Welcome to Burlesque," backed by a chorus line in fishnet stockings and eye-popping bustiers.
"Diamonds Are a Girl's Best Friend" is a nod to '50s showstoppers, "Wagon Wheel Watusi" leans toward '60s pop, and "Something's Got a Hold on Me" and blues pieces add a touch of soul.
Her big voice echoes as she shimmies through each song and dance number while coquettishly winking at the camera. If Burlesque was just an Aguilera stage show, it would be completely satisfying.
Unfortunately, movies require actual plot and dialogue and when it comes to both, the film leaves much to be desired.
Occasionally, a number takes place in the mind of its heroine.
Perhaps the entire movie actually takes place there.
