Breja: But then again I don't like the Infinity Engine games and I think Gothic is just an utter unplayable mess, so what do I know :D
OneFiercePuppy: <gasp> You don't like Baldur's Gate 2? Boo is heartbroken. See his little snuffles? A giant space hamster of proper size would shed a tear which would wash away the grime and villany of your disregard but Boo is miniature so you are spared this time.

I've decided that I really don't like the IE games either. In my case, the biggest issue is that they combine the flaws of turn-based and real-time combat while lacking both the rhythm of turn-based and the fluidity of real-time.
There's also some other issues:
BG1: Much of the game takes place at low levels, and it takes too long to reach level 2. Low level AD&D is not fun, because attacks keep missing, and your characters can get killed by one attack that decides to hit (and, to make matters worse, the death's door rule is not implemented for whatever reason).
BG2: Way too much dialog, including some related to time critical quest events, that is initiated by the game (rather than by the player). Also, way too many time sensitive quests, and it's easy to get involved with multiple quests at once, and you can't easily control that. Also, the selection of recruitable characters has some gaps, like not having a basic thief who can level up and be used throughout the entire game, and not having a fighter/mage of any sort, plus the fact that the romance options are not balanced for different types of character (3 for straight males, 1 for straight females (with someone who isn't the nicest IIRC), and no non-straight romances; I would have preferred for that aspect to be cut entirely rather than implemented in this sort of biased fashion).
Edit: A couple other issues:
* You can't control your characters directly. The only way to get your characters to move is to click with the mouse and hope the pathfinding does not misbehave. The arrow keys only serve to move the camera, not your character. Furthermore, characters don't stick together when you do move them. (Ultima 6 handled this much better.)
* When you die, there is no way to see the combat log. This means that there's often no way to figure out *how* you died, and therefore no way to learn from your mistakes (or bad luck).
