Gotham has really impressed me so far, at least with the assumption that the following eps are as well-crafted as the first two. The visual aspects are so stunning that it's easy to think that the show is mainly style, but there's quite a bit happening on many levels if you either pay close attention or simply rewind and rewatch.

The villains are particularly well crafted. Selena Kyle / Catwoman (who isn't, yet) is a spin I haven't seen before, and very intriguing. The actor playing the Penguin is fabulous-- this may turn out to be the best version of this character ever.

There was quite a lot of hype for this show pre-debut, but this may be a case where the hype was valid.
