Colony was a TV series about a post-invasion Earth, but almost all of the conflict is between collaborators and freedom fighters. You'll barely see aliens for most of the show.
It only ran for 3 of its planned 5 seasons, and it ends abruptly with no clean ending at all. But it is still pretty good, mostly drama and hardly any sci-fi in it at all. Sadly even dumbed down this much for mass audiences wasn't enough to draw enough viewer share and its cost to produce thus doomed it even though it hardly contains any expensive costuming or effects.
It's disappointing that we can't have nice things, but unless a show is a soap opera or about kitty cats or pap sports or caped spandex the audience is just too small.
So
Colony is just one more unfinished work among so many. It is still worth watching though considering how little there is to choose from.
Right now it's on The Roku Channel.
