2. Give The Audience Some Credit
There are many reasons filmmakers give for messing with the source material, one of which is putting the story in a way that the audience will understand. If this was really an issue then the horror genre wouldnt exist. A soon as it was revealed that a little old lady was killing youthful campers who had super strength from pent up sexual frustration at the end of the first Friday the 13th there should have been rioting in the streets. Audiences can put up with a whole damn lot, except for Showgirls, no one deserves that. If they couldnt, the film genre could not have survived this long. That throws a lot of the writing decisions right out of the window, including retelling origins. First of all, an origin is a quasi-necessary evil in storytelling. I say quasi because not every character in a story needs or gets an origin. Whats Perry White's origin? Who even cares? Origins are thrown in because the writer has to start somewhere, how the character becomes the character is as good a place as any. However the origin typically does more harm than good, and never ever helps the character grow. Bruce Wayne sitting in the rain next to his dead parents is the anchor that holds Batman in place; its the primary justification for why the character can never change. If I had a nickel for every time I heard Spider-Man do the great power line I would have bus fare at the very least (cmon dude inflation), after a while it just gets old. Filmmakers have decided to make matters worse by improving on the origin, which takes balls on a level that no one has the right to claim. Improving an origin is like improving a child birth, the only real option is to somehow make it not child birth. Retelling the unavoidable aspects of a story that dont always have a lot of bearing on the story the writer wants to actually tell is wasteful and insulting to the audience. There are too many genres and films to even assume that the story is going to go over the audiences heads. Look at it this way, does putting tights on a hero immediately delete the idea of the classical hero from a viewers brain? Robin Hood wore tights. John McClane overcomes impossible odds to save the day (without a detailed origin mind you), if he wasnt a cop but instead a bad ass with a mad on for criminals are audiences going to leave the theater hurt and confused? People who make comic book movie have a ton of excuses, which is a sign of being lazy.
