Grindhouse is just a term for the kind of place that would run movies to death until the films would pretty much vaporise. They would grind down the movies reels until they were unusable.
They used to play ultra cheap, disposable movies that feature ultra violence and gore, sexual content and crappy production values because that's pretty much what those theaters could afford as opposed to to the more fortunate theaters would afford better deals and play big productions instead.
The fucking intro is 5 minutes of Rose stripping, Planet Terror has tons of story holes, deus ex machinas plot points, over the top violence (the massive blood explosions every time someone was shot (which is a massive reference to the ultra violence of movies like Shogun Assassins/Lone Wolf and Cub) , massive sexually charged material (the underage twins, the stripper girl, the long shots of Fergie's close-up back and cleavages, and so on).
Death Proof had a lots of good things going on for it, but there was some real pacing problems. It still had a lot of sex appeal (the way Jungle Julia danced, etc). DP was more of a lazy effort tho, which is why lots of people don't like it.
Why don't you just go watch tripe like 300 and Will Ferrel movies instead. it's certainly more into your range of things, FOC
