Sitting in the movie theatre, watching this with my teenage son, I found my stomach quite tense/nervous - something it hasn't felt in awhile (last time, was when "Alien" first came out / the first time was when they handed me a barf bag for the premiere of "night of the living dead" in '68). The movie takes off like a rocket and the action doesn't stop 'til the end - and that's when you suddenly realize the ride is almost over and you start wishing for more. After years of hunching over our CRT, killing zombies and other dead maniacs, finally, someone in the last decade has made a decent "kill-the-dead-thing" flick. Hopefully Director/Writer Paul Anderson will at least equal this in the upcoming sequel! Our only regret - not enough screen time for the mutant dogs.
