Well, I just saw it and I am pretty impressed. Maybe a bit slow to begin with, I kinda wanted it to snap to the good stuff. When it did, It was glued to the screen. QT put in his work near the end IMO. The gore was all there, none of it too gross except (SPOILER) when the man was forced to cut the womens eye off, the puss was a little stomach churning and (SPOILER) When the guy was vomiting while having a gag in his mouth
It left me with WTF in my mind at the end. But I still enjoyed it. Particular favourite bits where when (SPOILER) The man was tied up and the surgeon brought out the chainsaw, that bit was obviously looked closely by QT
There wasnt really any plot to go with all these moments, the only clues where when (SPOILER) He met one of the surgeons and the surgeon was talking about the money he was getting from all of the killing he was doing
Overall, 8/10 for me, was better than The Hills Have eyes.
If you can deal with Gore, nudity and disturbing scenes I recommend this one.
