The recent cycle of Marvel films (Phase Three, as the production-company calls this series of movies) has taken the action to higher levels but also become much bleaker. After the gloomy ending to Avengers: Infinity War, there was hope that Marvel studios would wrap things up in a more optimistic manner.
Though they left themselves little room for an upbeat finale, there was a lighter finish, albeit with losses along the way.
To some extent mirroring the mood in the USA, these films have drawn in a range of issues to their narratives. As well as threats from the outside there is also the conflict between the characters themselves and the dominance of white males in key roles. This film deals with some of these but they, as usual, suggest that most problems can ultimately be solved by (justified) violence. The Avengers, like the USA, always come out as the unelected police force of the world.
