Eh, I liked DA2 for the most part. Yeah, I hated the recycling of environments, and the story completely fell apart in the third act, but overall it was still good. It certainly wasn't complete trash.
Personally, I don't think it fell apart in the third act even, excluding one choice which was immersion-breakingly railroad-ish. The environments thing was annoying, but the DLC (Legacy, at least; haven't played others) showed that they got that feedback and made some great new visual areas. DA2 is honestly one of my favorite RPGs. I went into it almost totally blind and had a blast. I had no idea what the overall fan-reaction was since I only saw a small microcosm of reviews before diving into it. I was positively aghast when I realized how hated it was! I seem to like a lot of terrible games.
