He's an OTT character who has made his gimmick work, he used to be Mike Dalton ffs, the Bo Dallas of FCW, and now he's trying to make something of the gimmick he's been given and is doing so, he's highly entertaining, him and Enzo are my faves on the NXT roster right now.
Because he have a good gimmick, that's all. NXt is different from some crowd, they don't care that much about the heels and the faces. They like someone, they cheer him, they hate someone, they boo him. Just here to have a good time
