I really wish those were real trailers... Heh, I'd SO pay to see Thanksgiving and Don't!
I expected to like Planet Terror more, but I ended up liking Death Proof. They were both awesome, but as Jetbaby said, it was fun to see the different sides of Kurt Russell's character, even the "screaming like a little girl" side

The talking in it didn't bother me SO bad, especially because afterwards the movie rewards you for it with one of the most suspenseful scenes in the whole movie. It was worth sitting through, because I mean, it could have been worse... the conversations could have been REALLY unnatural-feeling and downright painful to watch. The only thing I got tired of was the build-up to the game Ship's Mast - it got a little old hearing them argue about it.
I also like that QT had cameos in both of the films.
One reason I also think this movie did worse than Are We Done Yet? in addition to Mr. M's "Rated R" explanation is think of when the movies opened: Two days before Easter. Families come together on holidays and bring the kids along as well of course, so it's only natural that if they're going to see a movie, it's going to have to be a family-oriented one. Had it been on a non-holiday weekend, the outcome would have been a little better, I imagine.
