As for the production, the site believed that "Gotham" Season 2 might have 22 episodes. They also noted that despite its success, the TV show still encounters mixed reviews from critics. Few problems were cited including the inconsistent screenplay and being backwards compared to the whole Batman mythology.

Actor Leo Fitzpatrick is said to join the villains as Joe Pike. His character is the leader of the arsonist group called "The Pike Brothers." Though Joe Pike is not part of the traditional Batman mythology, things might not end up well for the chacter, Screen Rant noted.

Another actor that is said to join the series is Michael Piklis. He will be playing the role of the new GCPD Captain Nathaniel Barnes.
