I know! I saw GameXplain criticizing it and they're just outta their mind. Constantly pulling ghosts can get monotonous, and considering Dark Moon had already found a way to speed the process up, the slam just feels natural and so satisfying.
Same, I could do it all day. Especially when you slam a whole group of them. Also the bosses use it really well. I had one boss fight that was more like a war than a fight, I loved it.
I was really surprised with GameXplain's review. But Andre is the weakest reviewer they have, so whenever he reviews anything I don't take it too seriously.
