Box office increased for Spider-Man, Dr Strange, and Guardians. Slightly lower for Thor. Markedly lower for Black Panther 2 and Ant Man 3. Not great for Shang Chi, Black Widow, and Eternals. Abysmal for The Marvels. The BO increases were peppered throughout the post-Endgame slate, so I don't think we can just say it's slower post-Endgame in general. But my point is that they have/had a winning formula. Changing SS to a woman is not part of that previous winning formula... I don't think they did anything like that during the Endgame era, other than The Ancient One (who is not particularly a "main character" in the comics. Important, yes... SS-level in a Galactus/FF movie? No).
Can you name a few "important" difference on the level of changing SS to a woman, during the Endgame era? You may be right, but I am having a difficult time thinking of any such differences.
But why only The Marvels? Why didn't GOTG3 get hit by that slump/trend? Does The Marvels get a pass for some reason? It sort of feels like people wanted GOTG, but they didn't want The Marvels.
Agreed that it was definitely not as prevalent as Opp or Barbie marketing. Was it marketed any less than GOTG3, do you think? Or Ant Man Quantumania?
Correct, they have been doing so for the last 15 years. The majority of Endgame era would fall into that realm of "using the source material". That comment was more directed at SS gender swap. Why not use the source material for SS? Why not stay true to the character?
