Boogeyman was a great novelty character. Not really sure why WWE got rid of him really. I can see the age factor, but the man was in incredible shape for his age, and had a very good physique. Plus he was over with the fans. I think it would have been beneficial to keep him around for a while longer than they did.
As for Big Daddy V, I liked him best when he was under that very moniker. I was never into him when he was Viscera the goth, or when he was the 'World's Largest Love Machine'. Both those gimmicks sucked to me.
As Big Daddy V though, with Matt Striker as his manager, he was legitimately a threat and looked far more intimidating. I loved seeing him manhandle people and just dominating people.
Plus, the man was pretty quick considering he was 6"9 and 500lbs. I mean what other guy that big hits a spinning wheel kick? I wouldn't mind seeing him come back for a couple of years. I think a few younger guys would benefit form going over a huge monster like him.
