The latest estimates on the Bad Blood buyrate are between 300,000 and 400,000 buys (probably towards the 300K-side, however). That would make it slightly more successful than Backlash, but slightly less successful than Judgment Day. Since WWE considered the matches it was giving away at Bad Blood tremendous, this is certainly not good news for the company, especially for the hard split.
As indicated, if Bad Blood had a weak buyrate, WWE would be in a dilemma. Since the fact that the show was weak means nothing for the buyrate, the card of Goldberg/Jericho, HHH/Nash (in HIAC), Foley’s return, Flair/HBK, Booker/Christian, and more should’ve drawn a spectacular buyrate, but didn’t. This means that fans weren’t interested enough in this card to buy the PPV, a bad sign.
