Planet Terror is the movie I always hoped for when I went to the drive-in; Death Proof is the movie I usually got.
Two criticisms: see the girl in the poster? Showing us how she got that way is a bad idea. It's just a letdown.
Also, the eight or ten female characters in a film should not all talk exactly like the film's infamously motormouthed director.
That said, the whole package was a hoot and a half, and if another installment came out every month...I'd probably never see a respectable film in the cineplex again.
