Terribly clichè choices, dues ex machina after dues ex machina. There is not really a soul on this production as it just seeks to burn screen time to put characters in the same near death situations they escape from. When you have an overly protected maincast all the dangerous choices the producers give us because routine and boring. When the action is not going there is ample "hang out time" but it never adds up to much compelling characterizations. The cgi monsters become very replacable and it's always obvious the creatures never actually interact with the real enviroments. The worst offense of this, was in the Season 3 mall ending. But Season 4 just is all of this in spades.

If you want actual compelling Sci Fi with a horror twist I suggest Dark, Black Mirror or Something in the vein of Blade Runner. It is hard to care about characters in such clichè and overtly protective choices.
