The thing I disliked about the sequel was that it revisited some of the locations from the first game, a bit too much in my opinion, which kind of felt a bit lazy. I would have liked some new locations instead. I mean, sure, the aftermath of Dantooine was neat, but we also got Korriban again. Replacing those with original locations like the others in the game, and I think the game would have had more going for it.
I also felt like the companion alignment was buggy. I so wanted to try to get the handmaiden to the dark side, but for whatever reason, maybe it's the dialogue choices, but it would often reset, and when late in the game, you don't have enough dark dialogue choices left to sway her again. It kind of made the companion alignment feel pointless.
