This movie is awesome, I highly recommend it to anyone that is going to see a grindhousee flick and I mean an actual one. Grindhouse and machete aren't evem close to it in terms of grindhouseiness.
Before you go to see it, ask the theater if there are any sound issues. When I saw this last week, about 45 minutes in, the sound was delayed for about half an hour. I guess all the reels had this problem.
Funny thing is we snuck into this movie and the theater gave us a free voucher for the sound screwing up.
