Dark matter was pretty good, to me felt like a worthy successor to the whole stargate franchise - it mixed serious and interesting issues with cheesiness in just the right proportions, imo.
But they cancelled it, despite the show having the sexiest androids in tv history
And yes, I mean plural - Ruby Rose as the sex robot left me drooling. Which probably says more about me, than about how hot she is (very).
As for Killjoys - I've yet to see it, in fact I'm surprised there's a sf series i have not even heard of
Will investigate!
