They over-complicate the stories. Look at Ant Man. 1st movie - Heist. 2nd movie - fugitive. 3rd movie - fighting Kang and his army to prevent them from coming out of the Quantum Realm to take over the world.
DC had the same issue with WW84. If they got rid of the the Maxwell Lord / Wish Stone crap and Diana wishing Steve back and just focused on WW vs Cheetah they could have had a winner.
