I have never expected ITSV quality honestly. Nor have I expected SM2 quality. I more or less expected same quality as prior 2. Like the old saying goes, 1 is a fluke, 2 is a trend. Never really expected something Cap 2 quality from the same team as the prior 2.
I mean, I feel like "same team" is more fluid in the MCU's case. A lot of the people that worked on the prior 2 (Feige and some of the writers) also worked on a lot of great films within the MCU. Maybe ITSV is a high bar but I was hoping for something as resonating as Endgame or DOFP (it being a send-off film and all).
Obviously we will have to wait and see, but I will say I liked the first trailer more.
