The best part of this movie was the Dibs I bought before I walked into the theater. The worst part of this movie itself and the Dibs lasted about ten minutes.
It was not nearly as funny as I expected to be, given the cast involved. Breaking the fourth wall was clunky at best. I'm used to zombie movies where the cause was something man-made but this movie seemed more "preachy" than those. I want to be entertained, not preached to. Combine that with the fact the ending just plain sucked, and I'm feeling like I wasted not only my money but my time.
Tilda Swinton is the sole redeeming person in the movie, though her "ending" left me scratching my head. It made no sense whatsoever.
I don't normally review movies I see, but this one was so bad I had to.
