It's worrying how often we're getting these threads at the moment.
It really depends on what criteria you use to judge the quality of a championship feud. The writing in the Wyatt vs Orton feud was much worse. And the match quality was somehow probably worse too. But the sheer lack of star power or fan investment in this feud is probably a record low.
The feud does suck. Honestly I have watched almost none of it, because it's basically stopped me from watching Smackdown. Even the pay per views, which are the one thing I used to watch without fail. I've missed the last two Smackdown pay per views now and don't see that changing soon, because I just don't give a shit about a show with Jinder as champion. You know a title feud is bad if it's already turning off the audience before they even get a chance to do anything. But for what it's worth, I have looked at the results for some of the shows since then and it sounds like everything they're doing with the guy has also been pretty bad.
And Orton is not the guy to carry a nothing to an entertaining title feud right now. When's the last time anyone gave a fuck about Orton? He's the most overexposed, yet somehow underdeveloped wrestler in the whole company, and the fact that it doesn't feel like he gives much of a shit doesn't endear him to fans either.
Jinder vs Orton would have been a perfectly acceptable mid card feud, while the more talented section of the roster (Styles, Owens, Zayn, Nakamura, Cena, Rusev) competed at the top of the card. They've got everything completely reversed right now and it's not just hurting the WWE title feud, it's hurting the whole show.
