Honestly mainstream audiences just mainly like photographs. Illustrations golden age has sadly past.
Also actor's contracts often have a big influence over how a movie poster looks like. Mnay contracts demand that their star's face must be as big as or bigger on all publicity materials.
That's also why lots of independant movies will have the cooler looking poster. Studios pay big money to buy these stars celebrity appeal and want to use it. SO they end up sticking a ton of famous famous faces on a poster rather than coming up with a cool story appropriate design.
Lots of politics at hand in these multimillion dollar affairs.
