Going to my first AEW show! What should I expect?

Let me start by saying, I've been to several WWE shows. Raw, Smackdown, few house shows but this will be my first time at AEW. I'm going to Dynamite on May 27th in Philly and I think I've got good seats. WAY less expensive than WWE is currently! This will also be my Kiddo's first ever wrestling show!

I'm wondering what to expect in regards to show length, wrestlers who enter thru the stands, crowd vibes, etc.. I'm trying to catch up on current storylines as I don't watch AEW on a weekly basis. (I don't have cable nor do I have HBO Max.)

All in all, just seeing if anyone here has been to Dynamite and how it was for them.
