I am too much of a wuss to really dig horror movies. I remember watching the first Halloween at my dad's house in the middle of the day with the lights on and being terrified. Anaconda scares me to even think about, right now I am a little scared. And if you are really looking to not be able to fall asleep or look at Ronald McDonald for a little bit you should see IT. I quit scary movies after seeing Section 9 though, that shit is too scary. Props to The Horror Digest for being able to do it, I am too much of a wuss.
I am excited about Scream 4 though. I have seen all the other ones and don't have any lingering "omgimsoscared" moments. I really enjoyed them more then anything. And Scream 2 inspired me to sing a partridge family song to my girlfriend in 8th grade in the cafeteria the day before she moved away. Scream 4 comes out on Friday and while I might not see it this weekend when I do I'm sure I will love it.
I had plans to put links in to the trailers for all those movies I had mentioned before, I got too freaked out just searching for them I only got as far as the first Halloween.
Also I just saw the first bit of footage from the new Planet of the Apes movie, I'm excited for that too.
