I agree about the dungeons, but the only thing wrong about them is that the innovative 3D maps would have been a good idea if resolution were higher than 320x200. At that low resolution those maps are too hard to look at, and good old 2D maps with levels like in Arena would have been better. Also the buildings don't make architectural sense (unlike Arena): even castles and such are like caverns, passages with halls but a lot of vacuum space outside.
On the NPCs' lack of individuality outside quest giving (so common in RPGs) I have a funny image from Daggerfall:
And do I hate magic:
