After reading the reviews i was dreading seeing the interaction between the knuckleheads. To my surprise, I thought they were a benefit to the film. I was expecting Quentin Tarantino death by dialog wasn't the case.
It was pretty good. Not perfect. But definately not a failure.
I thought the characters were good... At first. But the film just ran out of steam or something.. Perhaps it was all the reshoots but I just stopped caring.
Being chased by a cartoon monster lessens the tension a lot also.
