Cornette and Last break down each weekly AEW show segment by segment and every week they praise some aspects of the show and criticise others.
Not saying Cornette doesn't go over the top as that's his gimmick but to say they have nothing positive to say is simply false.
They praised how they handled the empty arena stuff and Cornette regularly praises Jericho, Darby, Jungle Boy, Sammy, MJF, Cody, Page etc. He was even forced to admit Bucks vs Omega and Page was great.
Fully understand issues people have with Cornette but a lot of the criticism I see directed his way seems to come from people who don't listen to his shows.
