So, I tend to stay away from the Horror genre. But its "It" so I had to eventually see it.
As a kid, this movie would have haunted me for weeks. I'd probably have nightmares for days.
As an adult, its got enough suspense that I was uncomfortable on my couch. I find that the climax of the movie was nowhere near as scary as all of Pennywise's psychological tricks on the kids.
Will wait for #2.
