While I am a fan of the saw series, I will admit that they are terrible movies. The first was the only one with an original idea, but it was crippled by horrific acting. Hostel was an awful film that did nothing but rip off scenes from Takashi Miike films. So much so that it became predictable. Hostel 2 was a terrible film notable for showing that chick from Welcome to the Dollhouse naked and covered in blood, and a pretty amazing monologue from Rick Hoffman. Perhaps Hostel 3 is amazing, but I really can't take any more of it. Saw at least has a mythology running through it, even if it is overly convoluted and contrived
Funny because Takashi Miike was actually in the first Hostel, so maybe he didn't feel that way or maybe those scenes were homages.
