WM9 isn’t really next level terrible from start to finish.
It isn’t good, but it is still an acceptable wrestling PPV.
I would say both WM2 and 4 are worse. 2 is just a mess production wise with the multiple locations, and 4 is painfully long and boring.
11 is worse as well. It is so bad and that main event has to easily be the worst in Mania history.
9 wasn't bad, but I always say I'm biased with 9 as it was my first WrestleMania. The issue with 9 was not the wrestling or the matches itself but the results, and the self-pleasing Hogan finish. So many non-clean wonky finishes as well.
Tatanka won by countout when really he should have won the title.
The Doink/Crush finish with the twin clowns was not clean, but in this case effective (there were just too many other funky finishes)
Money Inc retained the titles when the Hulkamaniacs were DQd (which in hindsight was a huge red flag)
Perfect and Luger match was lackluster because Perfect's back was beyond f***ed by this time. And if I'm not mistaken another screwy-type finish.
The Undertaker streak was kept alive (even though is was only an infantile 3-0 at this point) by a 'cloroform'-soaked cloth.
And then the whole 'Yoko challenges Hogan' ending.
The clean endings were a really entertaining tag team brawl between the Steiners and the Headshrinkers, and an oddly placed Razor Ramon squash of Backlund.
