I just saw grindhouse and loved it. I love that they tried to recreate an experience for the audience, though it seems america's rejected it.
As for the movies, I thought Death Proof was much better and truer to the genre. Planet Terror almost seemed like a parody of these types of movies instead of really embracing them, and went over the top to recreate the experience instead of the small things tarrantino did, like when russel bent down and the boom mic didn't catch his dialogue. That said it was hilarious and fun, and rose mcgowan was fantastic in it.
As for the long tarrantino takes, yeah, they are reminiscent of resevoir dogs but I caught something else in it, they really reminded me of late 60's godard films, in its length/long takes and dialogue and the way they captured youth and life in the time period. As well as kurt russel was so phenominal and he got the best out of Rosario Dawson. The car chases were so great as well.
so yeah, this was such a great experience and i'm real glad they did it. It sucks it has bombed at the box office, but hell, clearly something is wrong when wild hogs is the 150th highest grossing film of all time.
