I finished watching both shows the other night. Production was very good, so was commentary. I thought that Global Wars was the better show, my favourite match Lethal Twist vs Gujjar/Mike/Uno. Not a single bad match on the card. The TV deal announcement is pretty sick. "MLP Mayhem" is a great name, and it seems like TSN is a huge network (they air AEW apparently).
I thought that Uprising was decent. Slightly heavy on random tag matches. Dorada/Gujjar vs Clark/Crist was quite fun. Good Brothers vs Jean/Banks was surprisingly good, with a shocking finish. Main event was very good. I like that they had a story weaved throughout both nights to set up Grayson winning the interim title (though I don't like that it's an interim reign and not a real one). The shot of Grayson celebrating in the crowd was awesome. Also, minor nitpick - Gresham's entrance video still has his first name spelt wrong lol.
Overall, a very successful weekend for MLP.
