12. Gotham Knights
You might be surprised to see Gotham Knights up this high on our Batman show ranking, but that's probably because you didn't watch past the pilot (or even the first trailer). Admittedly, the pilot wasn't a great start and the trailer was quite poor, but once it got over those teething issues, we were left with a pretty solid show that was full of potential.
The last DC TV series produced for The CW, the show focused on Batman's adopted son Turner Hayes, who was framed for his murder at the hands of the Court of Owls. He, alongside the children of some of The Dark Knight's foes, teamed up to clear their names and find out who really killed Bruce Wayne. In doing so, they made a name for themselves as Gotham City's new protectors.
The show didn't exactly reinvent the wheel but it did provide some excellent entertainment, thanks in no small part to its talented ensemble cast. Their chemistry is what really made Gotham Knights work and the more it grew throughout the season, the more the show benefitted from it, elevating itself from where it began.
I remember watching the trailer for Gotham Knights, hoping that once it overcame its initial set-up that it would find its footing. That's exactly what happened, as its intriguing characters and central mystery (which featured a pretty strong adaptation of the Court of Owls) guided it towards greatness. The fact that it actually picked up fans along the way (when it had initially lost them because of the response to the first look) is a testament to the hard work of all involved.
Gotham Knights really became that little show that could, and for a while it did. It's such a shame that The CW cancelled it when there was so much left for it to say.
