JONAH HEX - I think most agree that the movie a while back was just bad. I’d take a tv series and mix western adventure with other DC western characters (Cinnamon, Bat Lash, Scalphunter, etc ) and mix in some other DC time period appropriate characters ( Vandal Savage, Ras Al Ghul, a version of Swamp Thing, Baron Winter and so on ). Just use that time period of the DCU to its max.
That would be a way to add genre variety to the app.
Other suggestions??
