I just started watching the new season of Young Justice which made me think of the old seasons and recall that one of the things that is particularly original on this show and not on comics is that both Martian Manhunter and Miss Martian do not have Heat Vision but instead have Telekinesis. WHICH MAKES SENSE!! because fire is their weakness.
This also made me think of other examples of other media that are original there and not canon in the comics
like I always love that on Batman Begins, Bruce is trained directly by Ra's to be the next leader of the League of Shadows, the involment of Lucius Fox in the 3 movies is pretty much more interesting than anything else ever done with him previously and the interpretation of what happen to Joe Chill is by far the best version of that ever made
on the Arrowverse I loved that Oliver meet Deathstroke and Shado in the island and the overall relationship that this characters had. though what Lemire did with GA was also pretty good.
So anyone else has some other examples of stuff that is very good or interesting in the Movies and TV shows that should be taken by the comics?
