Great start, a lot of exposition but I feel like they got most of it out of the way. I was wondering if we would see Loki's response to Thanos killing him, so I'm glad we did already.
Lots of cool stuff in the TVA. I got a laugh at the drawer full of infinity stones. Basically the most powerful objects that drove the first three phases and now are just paperweights.
The D.B. Cooper flashback seemed out of place. Funny as a joke, being a bet with Thor, but why?
I figured they would be chasing a different Loki based on the stained glass window. Overall I think we are in for a fun
