Just saw Rodriguez' segment "Planet terror" at the cinema (both films were seperated in germany) a few days ago and was almost angry. The Weinstein brothers seem to be more wise than I thought because the original "Grindhouse" starts with "Planet Terror". It is faster, louder, bloodier - but it's not a really great movie as "Death Proof" was. Just a long, bloody Line of attractions put together. And it definitely looks like an expensive Hollywood-Feature and not like a 70ies Exploitation Film, no matter how many scratches are on the screen. All in all, it was sometimes really dumb and boring - "Death Proof" wasn`t. I know that this is unfair but I just tried to imagine myself seeing both films together with the trailers as they were shown this way originally. "Planet Terror" lost the game. It was funny and slightly satiric at some moments but not intelligent nor really entertaining. A good movie should be both. Maybe, the bad german synchronization (I had no choice as I visited a preview) gave it the rest. 
6 out of 10.
