It's been interesting. Much better than Outcasts on BBCA.
Have a bad feeling that it will be learned that the "mech's" are "piloted" by harness kids.
There appears to be some symbiosis between specific "skitters" and harness kids.
The scene with the skitter dogpiling with the harnessed kids looked like a protective type gesture to me. If it was, I don't see the skitters putting the kids in the mechs (though the question of why they are 2-legged when the skitters are 6 is another question).
I get the feeling that during the operation the reason the kids started to go critical is because the skitter was dead, which does lend credence to the symbiosis theory. Also, why did Ben remember his father when Rick didn't? Does that tie back to the skitter being dead? It also seems the skitters can transfer, or hijack the control of the harnesses as evidenced by the captive skitter using Rick to talk.
I just hope this doesn't turn into another Fringe.
