Disagree with the list. only to the point the man who wrote the list did not seem to read any of the comics at all. he is basing it on pre-conceptions or what he knows about a character or series from what he had seen in articles or videos. Any character has the ability to have a movie. but to film industry it has to be beyond the film to be able to make money of merchandise and make the name a household ideal.
There are so man dependencies to make a great movie, its writing, casting, budget. its a deep investment and a studio has to consider all these factors before dropping alot of money into it. if anything I think straight up animated movies would be better. the direct to DVD/BluRay is a great approach and DC makes great animated films. you can do more with animated than real life actors anyways.
