For me, DA:I is a pretty good-looking game. The environments feel large enough to convey scale, the castles you can explore do feel more like real places than they ever did in any of the DA games, and once you get some of the cooler environment events (like a Dragon flying overhead, landing and starting to battle a Giant, off in the distance) the atmosphere had me hooked.
That doesn't mean it's free from criticism though. Animations are still a sore spot for Bioware, with certain animations being reused from DA:Origins and earlier BW games, and they never seem to work quite right. I don't know if they look more natural on the human male than they do on the human female, but in almost every cutscene that features my character, I can't shake the feeling that humans do not work that way. Hell, the default stance and walk/run cycle for the human female character (which was copied from female Hawke's animation set from DA2) is still ridiculously overfeminized, with exaggerated hip swings everywhere (which could work for Mage or Rogue characters, but look a bit weird for Warriors in heavy armor).
Another point of criticism is that the main storyline tells you a lot about how bad the antagonist and his forces are, but only rarely shows it in any effective way. There is a certain quest early in the game that does a very good job at showing you the consequences of failure, but following that, I kinda lost a good sense for what the big bad is doing from moment to moment.
