The fact that so many people consider Funny Games simply a horror or thriller film demonstrates how successful and subversive Haneke's message really was...
I don't really think of Saw as masochistic, at least not the first movie, I think that it was just something really different with the horror-genre. The story was actually very well done, albeit in a different way, and at the time, the elements were fresh and kind-of unsettling. I will agree that as the series progressed, viewers got used to seeing the "torturing" and it was more for the fun of seeing the traps, however. I still really enjoyed Jigsaw's character though, or more so, the idea of him.
