Not a Tarantino fan I take it? This flick was classic QT. I personally liked Death Proof better than Planet Terror. And to answer your question, yes it get's MUCH better. The last race scene is epic!
On a similar note: I can't wait to see Inglorious Basterds this weekend!!
I actually am a fan, generally - Kill Bill & Pulp Fiction especially, but I also liked Reservoir Dogs. Not Jackie Brown as much, and haven't seen Planet Terror.... maybe I should have given it more of a chance - it just didn't grab me, and I was tired, and I'd had it for a week already, so I felt like it was time to send it back to Netflix... maybe I'll try it again another time.
I'm with you, though - Inglorious Basterds is a must see for me... Tarantino and "Nazi-killin'" - can a movie get better than that?
