I don’t believe many, if any, of the main massive comic events could translate to a live-action film, particularly based on the groundwork already laid out for the DCEU.

Darkseid war would probably make the most sense, but COIE would more interesting.

There's real potential in Blackest night and it would certainly be very different then what marvel did with Thanos.

I would say blackest night but the thrill of blackest night is seeing all these characters that died come back as zombies and torment the living characters with their mistakes which would probably take decades of movies to make work. I’d love to see Final Crisis made into a movie but that would just be laughably difficult

I would say Crisis. Cause they already did it.

Think Blackest Night would work best for it. They can't really do Crisis on Infinite Earths. AGAIN.
