Sentry is one of my favorite comic characters, so he is the focus of this review. Granted, Pugh's Yelena is the film's focal point, but her heroic arc does not focus on a big bad as much as it focuses on her shared trauma. They rearranged Sentry's origin story rather than abolish it totally. He is still a mental ill junkie, he just does not break into the lab to steal the drug but signs up for a study Close enough. The trailers for the movie are deceptive, as they waste little time introducing "Bob". The writing is not perfect in fact, it is a little clunky, and he is handled like Thor in the first Thor movie, depowered, because it seems to hard to write for powerful people if you are going by the examples we have seen thus far. But the big payoff is when they do have their throwdown with him, which does not shy away from showing how powerful he is.
The rest of the team finds the Red Guardian as the predictable comic relief, Ghost is still not really fleshed out, and feels different from how they appeared in Ant-Man & Wasp. Bucky and John Walker are at varied places on the static spectrum. I think bringing in Songbird, while they were at the Vault, might have worked better than Ghost or any of the original members. But what plays in their favor is that the movie does not drag; something is always happening, not a big action film, some fighting, but not loaded with it, yet it was well paced. The interesting change was how the VoidFre was handled; he was almost like Freddie Krueger if you replace sleep with the trauma of your past. When the Void is embodied as Sentry, it's not the movie's most well-written moment, but they get away from the tropes that often make all Marvel movies feel the same, This is what makes the movie stand apart from the other films, however if you go into this without watching "Black Widow" and "Falcon and Winter Soldier" than you might be a little lost unless you read a lot of comics.
