I agree with Iceman. I remember seeing clowns at the circus and such and they were okay, but I wasn't especially interested in seeing them.
I can't say they scare me, although, Pennywise was very freaky.

I liked the movie though.
When my kids were young they saw Poltergeist and they got scared of the part where the clown doll grabs the boy and pulls him under the bed.

They both say, to this day, that's why they don't like clowns. Then when they saw "It" that topped the Poltergeist clown.
I also agree with DMC. Supernatural type movies,although I love to watch them, scare me more than any other scary movie.
