I was watching before (barely), but he definitely piqued my interest to see how he would fare with the WWE style. And he's done well with it, putting on good matches with over the hill crap like Jericho or untalented crap like Roman Reigns. And it's been entertaining to see just how badly they killed his profile in less than 6 months.
Cant think of many on the roster I care about less. I enjoy his matches when I watch them...but he's a near on 20 year veteran who still cant cut a promo and shows zero personality at all. He's too much of a workrate mark and has never improved his other skills as a pro wrestler.
I have no idea why anyone would be solely drawn back to WWE just because of a one dimension workrate mark.
