The twenty-fifth TV show: #446 It
Not so much a mini series as a TV event, It adapts a Stephen King novel in two 90 minute parts. It feels like it had to be this way. A movie would have been a bit too much, too intense. Too many episodes and the arc wouldn't build as well, and possibly invite more speculation and analysis on something that you just need to go along with.
I'm not sure the eventual reveal quite worked for me, but the tension leading up to it, the way people interacted, was great. Especially the child actors, who did remarkably well considering the usual reputation child actors have. The special effects are good too, especially considering the TV budget, and are mostly very effective (except for some odd stop motion works that gets a bit odd).
Last, Tim Curry as the titular It doesn't have a lot of screen time, but he made the best of it. He overplays it just enough and it sets the tone for the entire series, making it big, evil and scary. It's a shame when he disappears, as it makes for the best threat throughout. Still, intensely tense and fun.
