So! I saw Alita tonight, and I really enjoyed it. The movie looks awesome, from Alita herself (those huge eyes never really bothered me, but about five minutes in, I stopped consciously noticing them), to all the other cyborgs, to the rough-but-livable daytime Iron City, to the nasty side that shows up in the night, to the fast-paced Motorball action, and basically everything else. I appreciated what they did with the plot and the characters, condensing things and throwing in some changes; I'm not sure how easy it was to follow if you're not familiar with the manga, but for me at least it worked quite well.
Also, it's the most obviously sequel-baiting movie that I've seen that also works just fine as a stand-alone piece.
