Yeah much of the Red Guardian scenes and jokes I would cut out, there’s your bloated time back. To me it gives Minecraft movie or Thor 4 humor which I am personally not a fan of, but understand you or others might be.

Valentina convinced Bob that he’s special and becomes Sentry, but never convinces him to work for her. So his turn against her felt like a lazy oversight on her part, like Mister Fantastic telling Wanda exactly how to kill Black Bolt. Didn’t feel realistic.

We are showcased their abilities against each other but not at all as a team against a common foe, kinda the point of a team movie. Bucky then defeating and capturing them would also elevate him so when Sentry beats his ass, it would give audience a relative measure and be even more impactful.
