It - Uma Obra Prima do Medo

That's what most of the other commentators say, and I can't disagree. Part 1 (or the first half, depending on which format you're seeing it in) is great: pitting some excellent child actors (including future star Seth Green of Buffy the Vampire Slayer) portraying some in-depth characters fighting against a demonic clown. The second half seems more like a "gee-wow - look who we got" self-indulgence at casting Anderson, Thomas, Reid and Ritter, with very little to make us care about these folks. The ending is also an incredible dumbed-down letdown, although in all fairness I don't think they could pull off King's ending, and most of the audience wouldn't understand it if they had tried. There are a few touching moments in the last half, and Tim Curry couldn't screw up no matter how bad the writing is, but generally the two mismatched halves make for a mediocre film when it could have been so much more.
