The best way that Marvel can fix this

So the current rewritten script is allegedly an abomination.



Fans also didn't like the idea of Pym being old and Wasp being his daughter in Wright's version.



Let's assume that Marvel can rewrite the whole thing, give fans Pym who has more sequel potential instead of Scott Lang who really doesn't and then give us the storyline where Pym goes crazy and hatches a plot to destroy a good part of the world in order to save it.
