#4 WWE's history of dealing with such out-of-the-box characters
Bray Wyatt and his Firefly Fun House are one of the most innovative characters ever produced in WWE. As much as the current segments have been a big hit, WWE's history of handling such out-of-the-box characters isn't that great.
The latest example of that would be the Broken/Woken Matt Hardy gimmick. After the huge success of this gimmick in TNA and rest of the world, WWE also tried to use it in their programming, but it's safe to say that they were unable to replicate the same level of success.
Even Bray Wyatt's old gimmick with The Wyatt Family had so much more potential that WWE did not explore. While the current segments of Firefly Fun House have been exceptionally written and directed well, I'm just afraid that they might soon become stale if WWE does not continue to push its limits and let this character become larger than life.
This is too good to be messed up, Vince!
