I'm with the lad on here that thought AEW went pretty stale and took a bit of abuse. Until about 4-5 weeks ago when it really started building for last night, I think it'd become pretty flat for the casual viewer. I get that for your hardcore it might be serving up far a better show than Raw & SmackDown, but I don't necessarily think that's enough to draw casual fans back and for me, NXT began to better it with ease (probably benefitting from a PPV being a little closer, too).
AEW definitely picked up in the run up to this, and I think I'd go as far as saying last night was the best PPV I've seen, with everyone raising their game as they should. I generally dislike tag team wrestling matches, and don't get the hype behind superkicking a c**t every 3 seconds, hot tags and the like, but every moment felt well thought out in that match and almost as thought it was proving a point that it can be far more than the usual tropes - it couldn't have been any better, really.
I didn't watch the women's match but every other match felt meaningful. Guevara v Allin (especially), Pac v Cassidy and MJF v Cody were all great, while Hager v Dustin & Jericho v Mox did what they had to do. Everything was entertaining. Sammy is ridiculously good all round.
Personally, I think AEW would benefit hugely from upping the number of PPVs they have. The gap between feels way too long and I think they'd be able to sustain momentum more easily with one every two months. Hopefully the War Games style thing helps bridge the gap to the next one a bit.
