I binged the four episodes of the season so far, and... My assessment is more or less in line with the majority here. There have been some good moments like the ghetto escape, or Weaver's moment with his altered daughter (and that made me think how much there is a lot of death of various characters on the show. Not enough for some but for me it keeps the danger level just right.), but... It really has not been focused, and this seems to be the general problem with the series each season. The difference is before it was the writing of the human characters, now, I just don't think that what the Overlords/Eshspheni makes much sense at all. I don't get what their game plan is or what they are after and adding in a fourth alien race seems a bit lazy. I generally like all the characters and some I am even fond of. But some have crossed the line of me not caring just because the growth for them has been nil or the writers have never had a good handle on them, like Lourdes. Again, I am invested in the characters and will most likely see this through to the end. But I am not exactly happy with how this series has been handled almost from the start. There's still potential there but it's starting to feel too late for this show to be more than just a summer time killer.
