This was a very good drama/epic/horror thiller. A group of kids are terrorized by a menacing, crazy, killer clown that unexpectedly appears to them individually to scare them and threaten them. Supposedly, it's a vengeful spirit of a man who worked as a circus clown and was killed. The clown is kind of funny, but is really evil. The kids finally get fed up with it and track it down and assume they have killed it in an underground water facility. But it comes back when they are adults and begins it's tactics again on each person. But now it's stronger and much more deadly than before. So they leave their busy lives behind as they return to their childhood Maine town to reunite and confront IT once again.
