What I loved most about these movies is that they really showed each director's style and blended really well with the Grindhouse genre.
Planet Terror was, like most of Rodriguez's films, very comicbook-like. It was loud, overexaggerated and just plain fucking awesome. Most of the aspects of that movie (Like Cherry's machinegun leg) were not realistic at all but. WHO CARES. Seriously. Just accept that its not going to be accurate in anyway to real life, its just fun. Plus you gotta admit, her spinning around and shooting all those guys and seemingly never running out of ammo was pretty fucking cool. XD
Now, Death Proof, at first I was thinking I wasn't going to like it. Like I said before. My thing with Tarantino movies, there is always something that I absolutely love about them. The music, for one was excellent. The car chase scene was just amazing, especially the nice little twist at the end. My god that was too awesome!
After seeing this a second time, I think I did enjoy Death Proof a lot more, but I still think Planet Terror was badass.
