I recommend watching it with low expectations. I did and had a great time.
I admit I got scared at first, cause the first scene of the movie has very terrible editing. Luckily, it got much better after that.
Sam Wilson is Captain America. He absolutely embraces it here. I can't wait to see him
leading the new Avengers.
Joaquín is far from the annoying comedy relief side kick people were expecting. The few jokes he has or is involved with, I feel most definitely worked
"don't say Ant-Man" 
He really feels like Sam's (unexperienced) protegee.
Harrison Ford makes the role his own. Less is more definitely applies here for Red Hulk.
If there's a scene I would've changed is (Big spoiler warning)
Having old man Steve showing up to give Sam the pep talk instead of Bucky. That would've been more emotional. But it's been like 3 years in-universe since Endgame so I guess we have to assume he passed away already.
Now what's interesting is that we have, at least, five current or assembling teams in the MCU.
There's the Thunderbolts.
With now a chance that Red Hulk, Zemo and even the Leader could join them in the future.
Also the new Guardians of the Galaxy.
There's the group that Miss Marvel and the new Hawkeye are assembling, that could either be the Young Avengers (most likely) or an adaptation of the A Force (since so far is only them and Cassie is mentioned).
Then there's the group that we see at the end of Shang Chi, with Shang Chi himself, Katy, Hulk, Captain Marvel and Wong.
And now
the new Avengers, with the members so far being Captain America and Falcon. If I had to guess, joined by Spider-Man, Star Lord, Namor, She-Hulk and Black Panther.
I'm guessing the teams will be meeting on Doomsday.
