I just saw it yesterday.
It was just okay. I really wanted to like it more than I did.
I thought David Harbour's Red Guardian was his usual charismatic loser-with-a-heart greatness, and Wyatt Russell's US Agent and Lewis Pullman's Sentry were good, but the rest of the cast was forgettable, and Sebastian Stan's Bucky/Winter Soldier could have been cut out of the movie entirely.
Then there's the writing...
There's no emotional center to the story. The characters lumber and tumble from one scene to the next. As asked several times in the movie, why are these guys hanging out together?
Then there's the visual concept: Here you have a collection of great hand-to-hand fighters: A Black Widow clone, 2 Captain America clones, Ghost had an interesting fighting style, but there's barely any hand-to-hand combat to showcase their strength.
Oh sure, there was that fight in the lobby, but....

...all that's for naught, as Valentina watches her minions get beat up for a few minutes, before getting on the PA and giving them an invite upstairs.
And then there's the sequence where they take down the big bad...

... Void/Sentry/Bob. Comic books have never done emotional psychobabble story resolutions well, and it certainly isn't pulled off here.
Was this the MCU movie that got great reviews, and was supposed to take the franchise in a new direction, and revitalize it?
Not on your bloody life!
