Why isn't Silent Hill 4 not much often talked about?

I've recently finished the game, and maybe I've a bad taste? Because I found the concept really interesting that you can physically travel between the real world and your dream (which are real places). Another thing I found interesting is it's true that people in dream often see themselves in third person perspective, which is beautifully portrayed here. The subway ambience was creepy. Although I know after some time the game gets repetitive, but I didn't find it that bad. What's your views?
