It's utter crap.
But it's also really pretty, and I want Sarah Brightman's holographic eyes and all the eyeliner in the world. And I'll probably go around the whole rest of my life saying 'reeeeeeeppppoooooooooommmmaaaaaaaannnnnnnn' and 'epilogue!' for no other reason than because it's catchy and rediculous.
Fun, but i think it rotted my brain.
EDIT: Also, there's Paris Hilton's face falling off in totally the least useful way, visually. And there's various incesty-flavored interactions. It would have been better with choreographed dance numbers. And the potential romance bits totally didn't happen, replaced by the afore-mentioned incesty bits.
