All of the 'E's slightly less than human gimmicks have evolved into fan favorites (Taker, Mankind, Kane... even the Brood came in a time where what they were doing was considered cool)
The Wyatt's were insanely over in NXT/FCW and for good reason... they remind me of the "The Doors" actually
Being unlike everyone else made Kevin Smith (think of 'Clerks' or 'Dogma') a lot of money in an industry which was largely cookie cutter and formulaic at the time
