…could it be the porn parodies do a better job of translating superhero costumes to the screen?

See for yourself:

The only problem with the article is that they assume anyone who reads it already knows what the comic book characters look like on the page and therefore can judge which version, porn parody or movie version, more adheres to the original comic book look of said character.

So, for those not so familiar with the comic book versions, these two of six of the examples stuck me as where the porn parody versions more closely adhered to the original comic book looks:

First up, Scarlet Witch, as presented in the comic books:

Scarlet Witch in porn (left) versus the way she’s presented (right) in the upcoming Avengers movie…

Rogue, as presented in the comic books…

And in porno (left) versus in the X-Men movies (right)…

As I said before, these two, to my eyes, were the clearest examples of the six presented showing that the porn parody versions honored the original “look” of the characters more than the “legitimate” film versions!
