Defiance has always had a strange sort of development speed. In the last season, some of the episodes were gripping expansions of the overarching story, whereas others were more episodic. This is part of the reason that I think its potential was never fully achieved, though it had moments which undoubtedly shone.
The first episode of the second season then (without wanting any above-the-line spoilers) mimicked it. There was a lot of hints of things to come, but it was still very much getting back into the swing. There’s nothing wrong with that, but I do hope it gets into the full swing of the story unfulfilled at the end of the last season.
