If he’d just said “don’t like this game, 2 out of 5” that’s perfectly fine, everyone gets an opinion. There’s just no way a game that has an otherwise glowing review should go from 4 or 5 stars to 2 because the reviewer didn’t like the voice acting, it makes no sense. It’s not even a narrative-heavy game, the voice stuff they’re complaining about is all inconsequential fluff.
