I hate to say it, but while they featured some very atmospheric art in places, the series, as a whole, seemed like a bit of a damp squib...
That last issue of the 'Aliens'-focused segment was basically one big excuse for a character to effectively say, "What does it all meeeeean?!" Reiterates a few fan-favourite 'Prometheus' theories and then goes nowhere with it.
To this day, I still don't understand how a synthetic robot was meant to have grown flesh, mutated and had its software programming altered. That entire sub-plot didn't make any sense, at all. It was like the writers got together and went, "How can we make a cool-looking version of Fifield?" But didn't think it through, logically.
