4) More Jonah Hex
In terms of guest stars, Legends of Tomorrow really exceeded expectations by bringing in Jonah Hex. Last seen being played by Josh Brolin in a terrible big screen adaptation, the show went a long way in redeeming the scarred cowboy, but there’s still lots more which could be done with him. His comic book counterpart is no stranger to travelling through time, and his history with Rip meant that the gunslinger fit right in on the Waverider when he boarded the ship.
While it’s hard to say whether he’s the sort of character who could be a compelling presence for the entire season, another episode being devoted to his adventures in the Old West definitely wouldn’t go amiss providing the showrunners can find an exciting new way to tackle it after his previous appearance.
