I still have yet to see Texas Chainsaw because it's only showing in 3D so far. But, other than a few people on this board, I haven't heard anything positive.... And while I've enjoyed all the sequels (which are all pretty terrible in their own right) and even the remake and it's prequel (which were better than they had any right to be), my favourite is probably the most despised:
The Next Generation.
Yes, I said it. I can't help it, it's such a guilty pleasure that's sooooo bad it's good. Glad to see there are 4 others (so far) like me!
