Seeing a 3 hours+ movie is some kind of a commitment, but I finally did it this afternoon, after having to go to work for less then 1 hour (systems tests, boring). It's pretty good overall, with some humour and lots of action. Of course, the Tarantino part as a good dose of dialogs as well.
In case you don't know, this is actually a double-feature, Planet Terror by Robert Rodriguez and Death Proof by Quentin Tarantino, with a few fake movie trailers. It's filmed as if they were old movies, both the style and the fake film defects, plus a few missing reels, for which "management" apologize, but they are of this decade, as shown by the use of text messaging on mobile phones in each movie. There is a little bit of nudity and plenty of gore & blood, which isn't usually my thing, but I expected it here and it actually worked. A few actors are in both movies, but for the most part, it's a different cast.
It did feel like 3 hours, but I wouldn't say I find it too long. It is 2 movies, after all. There's no real intermission, so if you don't want to miss anything, go easy on the soft drink!
In conclusion, get comfortable and enjoy the rides!
