Good things about Gotham:
Riddler
Penguin
Falcone, Maroni
Harvey Bullock (despite being different from his comic book counterpart)
Bruce Wayne
Zsasz
Bad things about Gotham:
Renee Montoya and Crispus Alan
Barbara Kane
Cases solved with leaps of logic
Bad writing masked by good characterization
plot moves to quickly (Gordon reinstated after one episode? COME ON)
Despite it's many flaws, I find the show extremely enjoyable. It and Hannibal are the only two shows I keep up with, barring a few anime (I have little patience with American television).
