If the game received a 6.5 from Polygon over repetitive gameplay, uninspired level design, and irritation over having to slog through 5 hours of game to play with your friends online, I don't think people would give a shit.
But the reviewer took issue with the art, and content. And for whatever reason, some people can't understand that a reviewer may not feel comfortable recommending something like this:
They're movie reviews where critics slam the violence for being gratuitous, or the sex is strictly for titillation, and has nothing to do with the film, and I feel people read those and think, "Shit yeah, this sounds right up my alley then!"
I guess I don't understand why if a game review is slammed for similar reasons, people can't say, "Shit yeah! I love big titties and I love poking warrior nuns! I'm fucking there."
Big deal the reviewer didn't like it.
