I liked its faster combat and skill refinement. I hated the dungeon repetition and lack of travel, which make it obvious that it was a rushed game of limited scope. That is unlike Bioware.
As for the story, I loved it. The dialogue could have been better at times, but not too bad. But the story was really interesting. There was a lively, palpable web of conflicting politics and the stories of how pretty much every race, political and religious group in the game wanted to annihilate all others and was led by selfish, greedy people were indeed fascinating. It was much deeper than Origins's "shadow comes, gather people and fight it".
