Everything about this movie is snapping. Both flicks are spectacularly entertaining. The point here is exploring action, editing, and just... fun. The point is that neither goes anywhere and that that is cool. The trailers before and in-between movies only add to the stew. Friends of Rodriguez and Tarrantino put in time on fake (?) trailers for movies like Don't, Machete, Shewolves of the SS, and my favorite by Eli Roth, Thanksgiving.
This really is a movie for people who revel in and adore "bad" movies. These guys really understand what made the source material so great and I think it shows the background that they bring to their more dignified longer form films. This is the raw stuff that they've wanted to do but there wasn't a place for.
The downfall that I can see is that people like sputnikjm3000 just won't get it. This is a movie that is meant to be shouted at and laughed at. It is big, loud, raunchy, vulgar, and fun fun fun. I think you need to have a certain amount of training in bad 70s schlock to really appreciate it. But I really really dug it.
