There are a number of Wonder Woman movies but not one movie with Rocket Raccoon as a main character and Guardians of The Galaxy Vol 3 where he actually did play somewhat of a major role to the movie. Note as well I found it on Reddit as a 10-year-old post so Guardians of The Galaxy Vol 3 wasn't out yet and basically yeah the first movie was still new so yeah 2014 is when this meme was made. Is the joke meant to point fun at the fact that people criticize Wonder Woman movies cause the most recent one at this time was in 2011? I honestly just don't get what this joke is trying to convey.
The joke would have worked better with Black Window instead of WW. Disney held off on any black or woman-led films for years (BW debuted in the third MCU film) because one executive (who's name I don't recall) refused to green light any project without a white male lead. It took over a decade for a BW movie and nearly as long for Black Panther.
