Thunderdome era network specials have been good.
Best thing on NXT in the pandemic era, aside from O'Reilly vs. Balor was probably the Kross interview on the NXT instagram page the night of Takeover 30, lol (it was well over a minute, so it can be found in the section for instagram TV posts on the profile). There was a hell of a ladder match on Takeover 30, for that matter.
I'd recommend the Dominik Mysterio tag match at SummerSlam. You should find it very entertaining if you're at all interested in seeing how he performs.
Bryan and AJ put on a real c-l-a-s-s-i-c on SmackDown for the IC title two nights before Backlash. AJ, Hardy, and Zayn had a great ladder match at the last PPV.
I've greatly enjoyed all the Orange Cassidy stuff on AEW, and the shows where Jericho did commentary.
Other than all that, there hasn't been much worth watching aside from a healthy smattering of various very good but not must see matches.
