So, in the interest of spurring OOC discussion (so we can get to the 2000th post and it can be used for something that isn't a GIF of Thanos dabbing), what is, all time, your favorite single piece of superhero media? It can be a movie, TV show, comic run, anything of your choosing.

For a comic book.

As far as shows / animation goes..
With the 3rd Season, Young Justice dethrones both Batman Beyond and JL/U on their shared throne where they've sat firmly since the end of their respective runs. 

And Live action movies.
Captain America: Winter Soldier's also worth mentioning as being the best Superhero movie. Endgame ain't far behind though.
