Well, he used to be a good fighter, and the Tito, Horn, Inoue, & Bas fights made me a fan for life. However, his current status is laughable, and his constant ego stroking has made me despise him. It's not a good sign when you can't stand your all time favorite fighter.
I guess some find his shtick to be entertaining. He's a "heel" or whatever to them. Personally, I just see it as a guy who knows the sport has passed him by, so he makes stupid videos, and never fights.
