Let me back up and give you some history: I grew up in a pretty conservative home, and wasn't allowed to see much in the way of horror movies (or, really, anything that wasn't rated PG). So there was no way my parents were going to let me watch the 1990 miniseries based on Stephen King's It, despite my penchant for scary tales. (I may not have been allowed to watch scary movies, but I loved horror novels - I think I read everything Christopher Pike ever wrote!)
But then I grew up and went away to college, and one night the miniseries was on TV again - and there was no one to make me change the channel, so I settled in for a good scare.
Tim Curry is the stuff of dreams and nightmares - I had seen him in the Rocky Horror Picture Show, and as the red devil in Legend, but nothing is quite as scary as Pennywise the Dancing Clown.
Quite some time passed before I was able to walk past a sewer without giving it an extraordinarily wide berth, or go into a bathroom without flinching if the sink so much as gurgled.
It's been at least twenty years since I saw It on TV, and I decided to bravely rent the miniseries to watch as research for this article. It wasn't quite as traumatizing as I recall it being the first time, but then again it was daylight and I was watching it on my computer screen. (Also, the late 80's/early 90's special effects don't really hold up.)
Maybe someday I'll be brave enough to read the novel...
