6) Write Out James Olsen
Like Martian Manhunter, James Olsen is another regular character who’s been underused. He’s suffered to a far greater extent, however. The problems started at the beginning of the season when Kara and James’ romance, which we had been built up throughout season 1, was artificially broken up. After that, despite being made head of CatCo, James struggled to find a place in the show. Even after becoming a vigilante in his own right – namely, Guardian – the character remained a spare part.
Unlike J’onn J’onzz, though, the best thing that the show can do with James Olsen is not to feature him more in season 3 but to cut him out altogether. With his status as the leading man of the show taken over by Mon-El, there’s simply no role for James to fill. And it’s not like National City will miss Guardian all that much, especially not when it has Supergirl, Mon-El and Martian Manhunter around to protect it.
It’s no fault of Mehcad Brooks, of course, who’s given the role his best shot. It’s just that this radically-different version of the classic comic book character has run its course.
