This show and really whatever Dr. S:MoM shows is really going to demonstrate how far the MCU has come since 2008. They opened with a movie about a not wholly unrealistic suit of armor. Shifted to genetically modified "monsters", Gods, War Heroes, then a massive film team up. All about as grounded as they could be even when they touched on a raccoon with a machine gun riding a talking tree.
With this though they're going full on comics on the screen. There's multiple versions of the same characters to keep straight, rewinds, infinitely powerful cosmic beings, etc. What's even more amazing is they're doing it well and without contradicting much that's come before. This is going to be a heck of a ride.
