Grindhouse: a fun double feature, but remember what you're watching

I had the opportunity to check out this opus from Robert Rodriguez and Quentin Tarantino last night. Lots of fun, especially if you have a couple of beers before viewing. The movie(s)format is definitely unique, trying and succeeding in accomplishing the feel of old sleazy double features from the 70s (or so I have to believe, too young to have partook), complete with (intentionally) scratchy film, missing reels, and lapses in dialogue. Adding to the fun, other horror movie auteurs such as Rob Zombie and Eli Roth have contributed fake previews to play during the intermission between the features. I loved the movie personally, but this is a case where the judgment call on whether or not the movie is good depends highly on the audience "getting it." I "got it", but I can tell that the humor and intentions of this movie will be lost on 90% of the general movie public.
Not that it matters. Stuff like this can last a long time if enough people go see it late at night on weekends (the time frame for which the source influence was made anyway). Not to mention the powerhouse that is DVD, which does a lot for niche productions such as this one. Furthermore, I do not know what made the people in the marketing department for this movie think that Easter Weekend would be a great time to release an homage to gorefest movies where the stories consist of a psychotic stunt driver who gets sexual gratification from killing women with his car and a zombie movie where the heroine is a go-go dancer with a machine gun for a leg.
Still, it's fun!!!
