Even during my first playthrough of Kingdom Hearts 2, despite how cool Auron is, I was checked out for most of the story parts of Olympus Colosseum. Frankly, I just didn't care.
It's also hard to get invested in the plot when the characters make decisions that I can only describe as nonsensical. As I said in the episode, when Sora volunteers to help Meg by going to speak with Hades, how did he think that was going to go down? Hades was the villain for this world in the previous game, and Sora should know he'd be up to no good. It just seems kinda pointless.
Nothing that went on here seemed to really matter, even to my younger self. Little did I know, right?
