I've heard it's not quite as good as you'd imagine it to be, but I still REALLY want to see it even just for Michelle Rodriguez. I know Jessica Alba's in it but I've heard her acting on screen is just about the worst you'll ever see :laugh:
The actual movie is based on the mock trailer they used on Grindhouse (Death Proof/Planet Terror) and was meant to be just a spoof but the fan demand ended up persuading them to actually make it. Rather like the Grindhouse films as well, underrated I reckon.
