I thought that the series was very engaging and kept me going till the end, but didn’t quite understanding the clunkiness of the robotic dogs, which were supposed to be these fearsome aliens. The scenario was starting to make sense when the two teenagers Sasha and Emily were both experiencing similar visions and experiences and also the reason for the abduction of the babies. The last episode showed someone in the spaceship that had the same tattoo as Emily and then it started to make sense, they had returned from another time and wanted to correct the wrongs of the human race by starting again. Hence the babies. Enjoyed the series.
