Thinner

...for a King work: they've always had a mixed track record. Generally this one is a tribute to the F/X wizardry as Robert John Burke goes through multiple transformations. That in itself is pretty horrifying. Most of the King subtleties have been sucked out of it, but what's new? It's basically a decent supernatural thriller. There is a slow, relentless horror to the whole thing, which doesn't rely on huge "jump out of the closet" shocks (although there are a few of those). Basically a horror movie for adults.
