I thought it was forgettable and formulaic, and the background mystery seems unlikely to ever become compelling. The characters all seem pretty flat and I don't see how that team meshes well together in the long run to make them a more interesting group. All I could think while watching it was that someone challenged J.J. to make a sort-of period piece, since they're all the rage, even though he didn't have a good idea for one.
Caveat that the above could be the bitter Fringe fan in me lashing out at its likely replacement for next season, but I saw it as Fringe clone with a weak premise and even weaker characters. Since this female lead is highly emotive, however, I'm sure it'll catch fire with viewers.
