People care too much if actor is good or bad for such roles. Only handful of characters needs good/great actors in comic book movies. Others is enough if they have charisma,charm,looks or whatever. Cavill, Affleck, Gadot, Evans, Hemsworth etc. all servicable for such roles. Especially these movies aren't like TDK trilogy and more like classic comic book movies. For a role like Joker, you need a top level talent. Wonderwoman/Aquaman not so much. Looks and charm are almost more important.
