Well, I heard some thought it was a heavy handed way of reminding the player that Gabriel/Dracula has really become a monster, but this reaction I would have never expected. Honestly, it's a scene depicting a monster feeding on his prey for survival, nothing else. A vampire sucks blood, sure there has been erotic implications in the mythology of the creatures, but it is really stretching it to construe the producer's statement that "we want you to feel uncomfortable" to mean "we intentionally made this scene rapey".
The weirdest thing is that the writer thought of it as similiar to such a notorious game specifically. Maybe she is really sensitive to the topic, saw enough of the "game" to be really disturbed (and why wouldn't she be, it's disgusting), and then was just suddenly reminded of it by the first person view and the hands? In the end, it's just an overreaction to a scene that sounds like it needed a little more subtlety in how it went about showing Dracula at his worst.
Most journalists who previewed the game recently have had a negative reaction in one way or another towards the scene, and descriptions of it do sound similiar to MW3's, "SHOCK AND AWE" scene, but I would not suggest censorship. The scene is meant to invoke a strong reaction, someone just took it a place it very clearly wasn't meant to be interpreted.
Also, some people say the kid was a boy, and some people say it was a girl. Some kids can be confused for either, but I was wondering if it's random? Like they are just a group of NPCs who wander around the area you start in, and the player has to actively hunt them? That would be a little creepier.
Oh yeah, and taking out the man first is just a survival tactic. It shocks the other victims into inaction, and he may have been attacked if he left one of the two adults alive while feeding. As simple as that, just vampire survival right there. It's brutal, but that's the point. We see Gabriel/Dracula's lowest point quickly, so that he can redeem himself to the viewer and his own dormant human side over the course of the game, probably.
