Grindhouse is nothing short of the most amazing cinematic experience I have ever had. You owe it to yourselves to go see it in the theater.
This one must be seen in the theater, or a drive in if I can find one playing it.
The DVD will undoubtedly be a poor way to experience this.
There is also some pretty cool trailers, including the first one I've seen for rob zombie's Halloween. I've never seen any of the halloween movies, but this one looks so good I kind of want to watch them all, just to see this one in the know.
