Or maybe, just maybe, the game just sucks? You don't get a "Mostly Negative" average review, consistently dropping for months, if you're just getting troll reviewed.
A lot of people are playing that game. This sounds like those reviews from people who have a thousand hours into a game and end up saying it's bad.
I've seen it happen too much, sadly. And if you read Steam reviews you'll know what I'm talking about. Not a lot of people have a real interest in explaining objectively why they don't like a game. A lot of external factors and silliness push the bias heavily. Sometimes is dev/publisher drama, sometimes is ideology, sometimes is the use of a certain anti-cheat software, etc. But all these negative reviews fail to mention whether the actual GAME is good or not. Which is what they should be doing.
