Initially an intriguing idea, but it gets weighed down with an ever increasing and unstable load of sci-fi flannel. There are some truly impressive moments but the two girl-boss characters very quickly become tedious and make the overall experience less enjoyable.
Why do so many 'strong female characters' have to be unlikeable, preachy, rude and unreliable? Who is writing these characters? Do they like women? Have they met any? And why do actresses line up to portray them?
Also, if the aliens are able to communicate directly with us now, and can disrupt communications and can force humans to see and do whatever they want, why wait for 400 years? Just destroy all humanity right now and arrive 400 years later to a pristine planet filled with wildlife and vegetation.
Unlikely I will bother with the next season if it happens.
