IF it's 3 hours of Pennywise actually being creepy and doing his evil thing.

My only problem with the first one was that the rest of the movie didn't live up to the opening scene. After the first scene you don't really see that much of Pennywise, just the other forms he takes.

From the trailers this one will show more Pennywise in all of his menace. If that's true than I will gladly sit through 3 hours of that.
