I think that Saga would work well as a tv series. It's got a very modern/millenial feel to it, has romance, a cute baby, action, a big ensemble cast and lashings of sex and violence.
Probably never happen. They'd need a very big budget I imagine. And I seem to remember reading somewhere that the creator didn't want it to be converted to another medium.
Would love to see Sandman become a movie franchise, doubt that it would ever happen.
The have made Lucifer a TV show which was a Sandman Spin-off
Nemesis the Warlock
