I'm sick of the kind of booking they receive, not them.
Bray Wyatt and the Family are some of the best characters on the show, especially when they're being used right. A deranged cult leader with a Messianic complex and a mostly secretive backstory is an awesome character, it's just that their booking doesn't (always) quite match up with what their dark and menacing nature is supposed to be, since Bray loses nearly every big feud that he's involved in (Cena, Undertaker, Roman Reigns, The Brothers Of Destruction, almost certainly Brock Lesnar when they eventually feud as well.)
The other issue is the lack of creativity with the group. There's a million and one creepy and disturbing things you can do with a crazed cult leader if you're willing to, why aren't they doing them? Not everything has to be another promo rambling about some allegorical end of days scenario or whatever. Footage of Wyatts in their old shack, maybe showing a gathering of the other followers that Bray has under his spell outside of WWE, etc. would be pretty eerie and cool. Watch some footage of real-life cult leaders to get a gist of what they could do. I wonder if their unwillingness to go to darker places with the gimmick has to do with laziness, or maybe because the PG rating might hinder some of the darker and more disturbing shit that the Family could do.
