It's hard to think what MAD can do if they drop the film parodies. I haven't read it for decades, though. TV parodies would still work - they're slower to percolate through culture. Does MAD even have a readership?
The whole Marvel/DC film franchise isn't worth the fluff in my navel. I was forced to watch a couple (Wonder Woman was the last) and they've all been CGI over substance.
You want a comic-book tie-in? 'DeathNote' and 'Full Metal Alchemist' on Netflix ('FMA' wasn't that good, actually).
