I liked Smallville, the story of Superman rising from the bottom of the totem pole, to becoming the very next hero.
I liked, no wait, I loved The Dark Knight Rises so count me in. Not a fan of many Batman films, but the current trilogy has convinced me that a show like Gotham can be good.
I have no problem with a Batman show that takes place before Bruce even becomes Batman. No problem whatsoever. In fact, it would help me fill in the blanks for some characters such as Gordon. I have wanted to know why people "look to him" like a legend, like everyone knows who he is. The origins of Joker, Poison Ivy, Riddler, etc. I already know about Penguin through Batman Forever.
