The Eye didn't look too impressive, so I skipped that one.
Horror movies haven't scared me since elementary school, but since I pretty much grew up on them it's hardly surprising.
I thought Hostel sucked. Only the last third of it was alright and by then I was like is that it? Up until the last third of it was just tame softcore porn. Not that there's anything specifically wrong with that, but I went in to see a horror movie so I was getting disappointed when I wasn't seeing human suffering on the grand scale that the advertisements promised.
And the only part I really thought stood out wasn't even any of the killing, it was the hyper businessman excitedly going on about killing someone and how much a rush he got from it. (That would probably qualify as the "scarier" bit rather than the torture porn stuff)
Plus the protagonist was completely unlikable, glad he got killed in the 2nd movie.
Hostel 2 was actually better since they dwelled more on the killer organization and the people that indulged in it. Which gave a little more background on the psychos. They were also more consistant with the killings and had a better protagonist.
The Saw series is one of those that's "meh". I didn't really like the first one and just thought of it as a lame version of Seven. The sequels sort of make it a little better since they start delving more into Jigsaw's mind and motives etc. Still, I think they should've just ended it at 3. Jigsaw isn't some supernnatural killer, and it's getting into the ridiculous with the series continuing AFTER he's dead. They pulled it off barely with 4, but I'm wondering how the hell they're going to do 5 & 6 without it getting excessively stupid.
One thing I probably can't tolerate in horror movies is crappy villians. Seriously "Scream" and "I know what you did..." had to be some of the most unimpressive and boring killers ever.
