I liked it. I thought the casting of Donal Logue as Harvey Bullock was brilliant and the guy who plays Penguin is great as well. My only problem with the premier episode is that jammed too many references into one episode. One of the great things about Arrow is that they limit those geek references to about one per episode. In this initial episode of Gotham we were given glimpses of Catwoman, Riddler, Poison Ivy and Joker. We get it, this is Gotham City.
The other thing is that I hope they’re not leaving the investigation of the Waynes’ murder as is. It could be a season long or even series long story arc and it kind of felt like they just dropped it at the end of the episode.
However all in all so far so good.
