I didn't like the style when I first saw it, especially in one of their first trailers introducing the new companions. It looked awful. But now that I've seen it in-game, I really love it! I prefer this art-style over Origins and Inquisition. It feels a lot like Dragon Age 2.
The dialogue and voice acting definitely isn't the best, but it's not the worst either. I'm 45 hours in at the moment and the dialogue doesn't get better. xD
It is interesting that you prefer this art style. I hope they don't make the next Mass Effect like this haha. But glad you really like it. :) I am only about 15 hours into the game.
