I think you encapsulated what Im starting to pick up on as well, the show is fading away from the start it had due to lack of character development. They introduced a number of plot lines early on that could have lead to more of this but the either quickly resolved them or just completely ignored them.
The first couple of episodes were awesome, the last few were OK. My enthusiasm and excitement to watch the series all lead from the initial episodes. Im hoping it recovers its swagger.
