Exactly, though even that is not much of a problem if done right. A smallville growing into the powers or an exploration of how carefull you have to be with such powers can also work, the Superman movies were shit because DC tried to write an elseworld story and forgot to hire a writer that makes them a good script or at least fully commit to the grim dark. The justice league stuff was just awfull because non-stop CGI, bad cinematography (that red filter..) and because they reworked it in editing. This has been analized to death, but nothing about these movies failed inherently because of the actors involved, they all could work given the right script/director.
