https://en.wikipedia.org/wiki/National_Film_Registry The NFR preserves movies in the library of congress. The film has to be 10 years old to be put into the NFR, as well as "culturally, historically, or aesthetically significant". Unless you count Zorro, there are, to my knowledge, currently no Superhero movies in NFR. In your opinion, which 10+ year old superhero films belong in the NFR? Which movies should be in the NFR once they turn ten years old? Do you think any superhero films deserve to be in the NFR at all?
