First thoughts - The poster looks really cheap even for a "teaser poster", and it looks like a bad photoshop of New York City instead of a grim Gotham City.
I'm going to stray away from all the negativity and stay positive about this show. The cast looks great, pretty good promoting, the character posters were phenomenal, I have a feeling 'Gotham' might turn out alright. To be truthfully honest, I don't watch a whole lot of TV as I use to, but I'm willing to watch anything that's Batman related!
In the comments section below tell me which villain are you looking forward to seeing in Gotham?
