BBCs Humans.

Had such an interesting premise of a rogue genius inventor sneaking in sentience of consciousness in his pet android project. Gemma Chan being in it made it a easier watch too.
But then they kill off major characters in later seasons for stupid reasons and then bring up the concept of a hybrid fetus....and the whole synth messiah god like arc was asinine. As much as it pains me, I'm glad that it was cancelled and we never saw that.... Plus
Tap for spoiler
the show could not go on without Gemma. RIP Mia.
It's been practically forgotten about
