Awesome Holy Grail ending!!!!!! (SPOILER WARNING)
I watched this last night and despite the fact that it isn't the greatest zombie flick ever made, as a spoof of the genre, I thought it was pretty good. Could have done without all the fart jokes. I mean, c'mon.
The ending, however, was absolutely freaking genius. It reminded me of the WTF? ending in Monty Python's Holy Grail with the cops rolling up on the cast and arresting everybody. Here the actors (and some crew) seem to revolt against the production and it ultimately ends the film just as the situation is ramping up to the finish.
It takes you by complete surprise.
