Personal like or disgust of subject matters in a product is definitely a factor that can affect someone's like for the game. It affects player engagement, and if the game doesn't engage the player, it fails to deliver a good quality product.
Reading the review, I see several things that sabotages the reviewers engagement of the game. Grind and bore related to shallow mechanics, and story elements that bury the experience for her. (I bet there are some people who play the game to see the next sex toy in distress picture... and speaking of target audience, perhaps the target audience excludes women...) It is clear why the reviewer would be put off by such things.
Not to mention that, as a reviewer she is obligated to play through the whole game, which quite likely exacerbates a reviewer's negativity from being unengaged by the game.
I think the review is honest. And you don't even have to be a fe(naughty word in this place) to be turned off by this game. If there is any bias, it is because, least I say it, the reviewer is female (and I will say the next part unapologetically). She just isn't into getting boners from those pictures NPC women.
Perhaps the reviewer finding the game getting more boring as it forces you do fight the same thing over again is another abhorrent bias (in seriousness. Longer ain't always better and padding can be detrimental to the experience, and overuse of padding is another legitimate detractor for a game).
Perhaps, the score is low based on the descriptions. But, perhaps the game really does get that boring if you grind it out for the duration of the narrative. Or perhaps the score is slightly negatively affected by bias. (Oh no, now the review is completely horrible and unwarranted...). I'd wouldn't blink an eye if I read the review and saw a score of 7. (thats a one point difference on the 20 gradation scale polygon uses).
