We skip Timeless River in favor of Port Royal instead.
When Sam and I talk about this game's tendency to just recycle the stories from the movies they source from, this world is one of the worst offenders. Not only is this the same exact story, but it's also the same shot more often than not. On top of the frequency in which they repeat scenes, it's one of the worst ones in the game. It exists only to capitalize on the popularity of the franchise back when Kingdom Hearts came out.
It's also just a strange world in general. The "realistic" visuals looked pretty good at the time, but it just hasn't aged well at all. By modern standards, it just looks too uncanny. And to have Sora, Donald, and Goofy is juxtaposed to the much more washed out visuals of the world and characters is even worse. Sam's right when he says it looks like it's from a different game entirely.
When I went through this level way back when Kingdom Hearts 2 first came out, I was impressed by it. That said, it doesn't hold up to the test of time. Nothing here is particular well done.
