I love Thunderbolts\*, but it came way to late. It's a team up movie that mainly ties together Phase Four projects such as The Falcon And The Winter Soldier, Black Widow, Hawkeye, and to a certain extent Black Panther: Wakanda Forever. That's four of the fifteen projects (excluding the two special presentations and I Am Groot) of Phase Four. While that's not great, Thunderbolts\* has ties to one other Phase Five project, that being Captain America: Brave New World, which had some minor setup for it. If Thunderbolts came out in May 2023, as the conclusion of Phase Four, it would've been a lot better in the long run.
Thunderbolts* should have been the movie to end Phase Four.
