The only thing I've seen of the Saw "franchise" was the end of the first film, maybe the last thirty minutes or so, and I thought it was decently entertaining. It reaked of a SciFi channel original, though. Low budget, campy dialogue, a mishmash of every horror film that came before it without much thought or effort given to an original plot or circumstance. Still, it could have been a lot worse, and it actually did make really decent money in the theaters for what it cost.
