I've only seen 4 of these:
Final Destination 5
The Human Centipede II (Full Sequence)
I liked Fright Night and Final Destination 5 well enough. Scream 4 was...about what I expected it to be. And The Human Centipede II lived up to the (mistaken) public perception of what the first one had been like - completely, pointlessly disgusting, with no story and no redeeming characteristics whatsoever. A big disappointment after the entertaining first one.
