Saw 3d was absolutely horrible, the rest ranged from watchable to quite good.
If you have an hour to burn, these guys have an interesting take on the series.

It's interesting though, that these guys repeat what I often hear in that everyone hated the movies initially, but after the writers began to connect and intertwine the installments together that they began to appreciate them. Aside from the last one I think they all have their moments, not the best horror fare, but not the worst either.
Has anyone mentioned Showgirls yet? Not that it's a good movie, but I'll always remember it for being the first time I saw full frontal nudity. I was 11 years old on vacation in Disneyland, and it was on pretty early at night. I had no idea what it was about, nor did I care, but I absolutely loved it for obvious reasons.
