I think Wonder Woman was a much better film than its immediate predecessor Batman vs Superman, and was recognised as such. Perhaps its popularity did get a boost from its feminist following, but I didn't see that strong an agenda in the film - she wants to save the world, and she happens to be female.
I don't know which Marvel movies you're talking about. Spider-man focused mostly on him and the other men, with a bit of story about his girlfriend. The Avengers has Black Widow having too much prominence along with Hawkeye and Captain America (they suck in comparison to the rest, at least in the films), but that's from trying to cram a lot of characters in and isn't a feminist thing. If anything there's a lack of female characters (in the source material due to lack of demand, which then gets carried through).
Can't really comment on the Transformers movies as I've only seen the first two, except to say that all the humans are given too much prominence in a film about robots that can squash humans by accident.
