Yea it sucks, but I can kind of see how moves from the grindhouse era went to theatres billed together, but weren't released on home video together, so it makes some sense, but still the point was a double feature.

the only thing that sucks is these movies are so good, I rented death proof and thought the extended version was way better, and I'll rent planet terror as well.

but definitely buy the grindhouse version.
