To be fair NOTHING when one of your executives was actively fighting to keep Black Panther out of theaters. Let alone be made because of DC's failures known as Catwoman & Steel. While ignoring Blade and his 3 films.
They still had to use unproven guys. Guys who did NOT have movies in theaters like Superman & Batman.
Tony Stark was having cartoon shows on Toon Nick when all this started.
Just because they have been SHOVED up everyone's rear end does not mean folks were going to support them.
Antman & GOTG were phase 2. Who was asking for them?
Marvel still took trash and made it work. And instead of burying competition-they embraced it.
Antman was not buried to force folks to like Tony or Thor or whoever in comics like so many at DC have been buried.
