I just got home from it about 15 minutes ago... We had several different events going on (i opted out of the star-studded premiere a week and a half ago) but I chose the all-night grindhouse marathon leading up to the 8AM showing of the movie.
Good and bad points on the event. good: I got to see 4 amazing movies before Grindhouse. bad: the 4 movies I got to see before Grindhouse were better than Grindhouse.
I liked parts of it, but don't want to shit on anyone's good time.
my movie journal will have more detailed notes for the curious... the jist is I liked Death Proof more than Planet Terror. Don't and Thanksgiving might be my favorite parts though.
