You know how when an action movie comes out, and there's always that one friend who hand-waves the special effects and assure you that it was a bad movie because good movies have good writing, and everything else is secondary to storytelling? You want to say "it's a visual medium, if all I cared about was the dialogue I'd read a book", but it's clearly very important to them that they be seen as as a higher-thinking connoisseur, so you just nod until they change the subject.
This is like that.
I'm not saying it's wrong to prefer a slower burn with realistic characterization, and I enjoy a lot of games that focus on those aspects. And I also understand that there's a whole world of porn out there that's just visuals, so it does make sense to encourage this medium to play to its strengths and not just completely ignore the plot.
I don't think this game does that, but it definitely cuts to the chase faster than I think most of us would like. (Although if we're talking about saturation, there are also quite a few games where climaxes -- in both senses of the word -- take months and months, often blurring the lines between teasing and milking.)
I think if this game had merely good visuals, I'd give it a 3/5, -1 for sudden pacing on the corruption and -1 for the generally barebones setup -- not terrible, it just doesn't stand out. But guys, these visuals and animations aren't just good, they're grrrrreat. I want to see more that looks like this. The story, including the visual aspects of it, e.g. the facial expressions and body language, is enough to check the boxes, and the visuals carry it from there.
It's a solid B action movie. Nothing wrong with that.
