Depending on your age and what you're exposed to, there has to be a movie that absolutely scares the piss out of you. Mine would have to be Pet Cemetery. I saw it when I was young and it's stuck with me ever since.
I watched the Leprechaun movie when it first came out in 1993, I was just a kid, but it had me scared of the dark until i was a about 13 or 14 lol I always thought a Leprechaun was gonna jump out from under our porch and eat me HAHAHA.....
Now I havent seen a movie in the last 15 years or so that has scared me, and honestly I've fallen asleep in several movies in a room full of screaming people lol they just bore me any more......
But that Leprechaun movie really messed me up as a kid thats for sure lol
Hm, I really have no idea as to why people find the Saw series to be scary. And if anything, I thought Billy [the puppet] was rather amusing. If anything, I absolutely love Saw. John Kramer had a very interesting ideology. I've never had a problem with gore (although I've probably only seen the very fake-looking ones like Saw and The Thing). Anyway, I'd have to say Halloween II (2009) was the scariest. I don't think I got past the part where Michael Myers decapitated a man with a glass shard; I was younger then, so I might do better now.
I get scared over pretty much every movie, but when I was young my older sister made me watch Nightmare on Elm Street. Freddie still creeps me out. The Ring is pretty creepy two. But this one is the all time scariest movie I have ever seen. When I was younger my sister got this movie FreakShow.(Or at least I think it was called that.) On the cover it said Banned in 43 countries. Just the music creep-ed me out. They didn't want me to watch it, they said it was that bad. I did though. And can I say, I'm never going to watch that movie again. It was not only scary, but disturbing.
Scariest? Hmmmm... Nightmare on Elm Street, the 2010 version. That movie is absolutely sick! The ending is so twisted.
I know I sound like a total sick person saying this, but the funniest scary movie I've seen was The Final Destination. The part where he says: "Could it kill you to be sensitive?". Me and my friend were cracking up!
