As far as any PC issues are concerned, I have a feeling that reviewers failed to mention those because they didn't review it on PC. The vast majority of reviews was published a week ahead of the game's official release, but PC graphics drivers that could run the game reliably were only published shortly after release. So IF any reviewer played this game on PC before release should have run into way more problems than we have today, but if they did, they chose not to mention it.
Also, how anyone who played a melee character for any amount of time could miss the messed up hit boxes that sometimes just don't fit the model of the creature they belong to is pretty odd. Maybe each and every reviewer was playing a ranged character on casual difficulty... but if not, it's a real headscratcher. It's not a minor occasional glitch after all, it's easily reproduced.
The closest thing to actual criticism about some of the stale side content that I read in a review was a sarcastic remark about how the Hinterlands sure had a lot of leftover letters lying around.
One way or the other, I still got my money's worth out of the game.
