This show to me feels very much like Babylon 5 season one. A trading post keeping the peace between different groups, and having our characters deal with a new crisis each week, while dropping hints of world-building and larger issues here and there. Also, the acting(mostly) and the characters don't really jump out and make me emotionally invested in anyone yet. And I felt much the same way about early B5.
Babylon 5 however had a strong showrunner with a pre-planned story, and enough time to tell it. And it of course became much, much more gripping in later seasons. I hope that happens to Defiance, but I wouldn't bet on it.
