Of all the WWE Events I've seen, Fastlane was definitely the most recent. Spoilers ahead obviously.
Shinsuke and Seth was great, and really the only match worth going out of your way to watch. Had a great build and considering how the faces won every other match (if you count Iyo Sky as a face) it seemed like Shinsuke might actually pull it off. But, he didn't. The match worked because of the bending back of the fourth wall in a good way. One wonders how bad Seth's back actually is. Hopefully it's not as bad as they make it out to be in the story because if it is, some of those bumps are really ill advised. Even if his back is fine, they maybe overdid it a little.
Everything else was varying degrees of good. Fun to see Cena back, and his match served its purpose of making LA Knight look good. It's one of those situations where you know what's going to happen, and it is what should happen, but still kind of hard to invest when the outcome is so obvious. Wasn't bad, but could have probably main evented Smackdown instead. Seeing Carlito back is fun, hopefully this run is a bit longer than the last where he popped up for a couple of weeks and then poofed away. Had to look up his age. Dude is 44. Absolutely insane shape.
It was a perfectly decent way to kill a few hours, but it was very sports entertainy. Aside from the main event, the matches were more about pushing forward certain stories than being great matches in and of themselves. They weren't bad matches, just not the kind of climactic fued ending matches that are generally the point of PPVs. Very much feels like they're trying to stretch things out till Mania season.
