It's quickly becoming a Christmas tradition for me: Midnight mass, opening presents, getting a bit of shuteye before.... before.... I go see the first public showing of a horror movie that hasn't been press screened. Can you guess where I'll be on Dec. 25? Don't misunderstand: I hope to be pleasantly surprised by Aliens vs. Predator -- Requiem. Contrary to what some of you suspect, critics really don't enjoy writing scathing reviews, because that entails having to sit through a crummy movie. And, trust me, I'm pretty whack, but I'm not that masochistic. On the other hand, I must admit: I'd be looking forward to this flick with a lot more enthusiasm if they'd figured out a way to drop a certain superhero into the mix.
