I liked a lot of what DA2 tried to do, and most of what I found lacking (at least on the second playthrough - I confess that my first impression was less positive since it wasn't what I was expecting from a follow-up to DAO) was completely due to the rushed release - things like the recycled environments and the absurdity of enemies falling from the skies. That those things were fixed in the DLC made it clear to me that the devs were aware of the issues, and I thought that was a positive as well.
The one element that I loved was the simple fact that it gave us a fantasy game that was driven by something other than a grand epic story - I realize that that's something that many people would call a flaw, but from my perspective that was a brilliant choice. I also liked the subtlety of impact of choices - I liked the variety of dialogue changes (I was still hearing new lines in my 4th playthrough), and appreciated that more than the dramatic ritual vs. sacrifice ending choices from DAO. And this is even more subjective, but I enjoyed the humour of the game, and thought that having a voiced protagonist aided that.
I'm also fairly neutral on the gameplay changes - I found combat to be fairly balanced, which is all I ask of a game (although to be fair, I generally play on hard, and a lot of the complaints I've heard were about the easiness of normal or the 1-shot deaths on nightmare, so I appreciate that there might be flaws there for others).
That said, DAO was clearly a more complete and polished game, so I don't disagree with people who criticize the game on those grounds, I just think that it's a shame to miss the things that DA2 did well, because to my mind when DA2 got something right those elements were brilliant.
