I liked episode, but i expected more J'onn J'onzz history, more action. I loved Alex and Kelly moments or Nia&Brainy, but William was really annoying. Reminds me Siobhan Smythe from S1. And why Lena is a villain. That is not fair. I want more things connected to Crisis or J'onn's history or Leviathan. That was dumb.
