Although there were a lot of problems with Ender's Game, I was a little surprised that they didn't adapt any of the sequels. I mean I wouldn't have watched them, but it seemed like they went pretty all in on that first one to not at least try the second with a significantly reduced budget.

We need History of The World Part 2

I’m way too late on this one but I’m going with Battle Angel Alita.

I'm gonna answer a slightly different question, What film am I surprised didn't get a sequel sooner? The Incredibles. Sure, it was a self-contained story, but it could've gone anywhere after that. The last scene with the undertaker was just teasing another Incredibles adventure. But instead we just kept getting toy stories.

By the time they did announce a sequel, it had been so long that I wasn't confident that it could live up to the original - and I was pretty much right, it wasn't a bad movie but I've never felt the desire to watch it again like I have the first a few dozen times. So yeah, that's one movie where I'm like "why didn't they ever make a sequ- ... oh, that's right they did"

I can't see anyone mentioning Titan A.E. man I love that movie, the mix of hand drawn animation and CGI was great for the time and I really enjoyed the world building.
