Nobody, because it's wrong.
Everything is going to make "a good amount of money".
BvS made "a good amount of money". Business is about maximizing profits on the properties under your control. They didn't with BvS, y'all refusal to admit this fact is laughable stannism to the extreme. The goalposts are different when you have a movie with top tier properties than a movie with some no name.
That's why your constant bringing up of Marvel being sad at Deadpool makes no sense. We are talking about the failure to take advantage of the properties under their control and y'all can't admit it so you gotta change the subject on some well marvel doesn't have Deadpool haha!
They literally added him and turned MOS2 into BvS because of the reception to MOS and their desire to skip steps to close the gap on marvel and get the JL popping. What
Batman was literally what was supposed to help push this into the game changer category, this was supposed to be an event with Americas two most popular heroes in a movie together for the first time. Batman is always gonna be the fail safe for this company because he rarely is received poorly.
