No, I don't care about the positive threads even. I've bought this franchise every year since 2K9 and I see for myself what's better each year and make my own opinion.
Saying "I hate this game and I'm trading it in" doesn't help anyone. There's nothing constructive to take away from a statement like that and it doesn't affect anyone in the slightless. That's why I think it's pointless.
Just the same as someone posting a thread saying; "This game is great!" doesn't add anything to anyone's experience.
