I generally don't like underwater levels either. And the thing is that I could enjoy them is developers weren't so dead-set on making the character/vehicle I have to move control like shit then they could be great, since quite a few of them are beautiful to look at.
Next up would be areas that are so dark you can't see more than a few feet in front of your face and sewer levels because they almost always end up being a maze of somekind and I hate that. And Dark Souls is guilty of both of these things (The Depths and Blightown). And Demon's Souls had some of that too (Valley of Defilement).
