It looks decent, i wanna believe that it will be good, this is their chance to make an actual good movie that is a good movie out of the mcu.
The 2017 mcu movies were very bad, Black Panther was good but it had some forced humor, but not as much as is often the case with mcu movies which they have lots of artificial jokes shoe horned in by disney. I hope the jokes are few and not out of character.
Another issue i have is how rushed and underdeveloped the mcu is even though they have been doing it for 10 years.
Also, some heroes seem to be missing, the movie will fail if at some point we dont get a group shot of all the heroes of all the mcu movies along with the "Avengers, assemble" quote, which is why i believe the true movie will be part 2 and this will be just the first half of a whole story, which all the previous movie were just a trailer for.
They have also made some aesthetic mistakes: Captain without shield/helmet, Thor without hammer/long hair, blond Black Widow, Spiderman with armor, but those are just details.
Anyway, i am sure that it will be entertainning and well made, but i hope that this time they really put some Marvel in it. Oh and more cosmic stuff, that seems to be lacking in the mcu.
