5) Give Us Lex Luthor
As well as bringing in Superman, Supergirl season 2 also introduced the family of his greatest nemesis, Lex Luthor. Lex’s adoptive sister Lena appeared as the new CEO of L-Corp and bonded with Kara as she tried to distance herself from her family’s wicked ways. Her mother, Lilian Luthor, was then revealed to be the alien-hating leader of Cadmus. Seeing as both Luthor women will stick around for season 3, it’s now time to introduce Lex into the mix.
In the show, his absence is explained away by him being in jail. But every Superman fan knows that the Greatest Criminal Mind Of Our Time does not stay behind bars for long. It would make for an awesome Lena-focused arc next season if her older brother got himself out of prison and tried to take back control of his company.
Just like it did with Tyler Hoechlin’s Superman, the show could give us a more traditional version of Lex. This is something a lot of us would like to see, especially to wash away the taste of Jesse Eisenberg’s odd take on the character in Batman V Superman: Dawn of Justice.
