While I agree with other comments that this season felt a little filler like, it was still great TV, so I find it ridiculous there are people seriously rating this 2/10 -- no way is this "terrible" TV.
Looking forward to season 5.
They try to mimic the atmosphere of Blade runner and Total recall, so you get action and effects. But i really didn't get the story and the motives of the character, and some things don't really make sense to me.
Watch it once if you have nothing else to watch, but don't get your hopes high.
7/10 for me.
Bad series with very unclear story, was a waste of time!
