I think calling He Man a superhero movie is a bit of a stretch. It’s a retro IP doing fantasy tropes for an audience that doesn’t really make much sense as people old enough to remember He Man as a going concern are pretty old at this point.
Last year’s Superman was a success by a director who has a good track record. This year’s Supergirl was a bit of a mess by all accounts so I’m not sure that’s much of an indicator. Deadpool and Wolverine made a kajillion dollars in 2024. Thunderbolts underperformed, but it was well regarded critically and was a good little movie for that sort thing. And it’s not surprising that “smaller” film with a bunch of self consciously D-list heroes didn’t pack em in. I would assume the Fantastic 4 movie was more of a disappointment.
Spiderman Goes to Hawkins and Avengers v. Oppenheimer’s Bad Guy will likely make a shit ton of money.
