Yeah, that’s probably the big one for me, with Jericho being a close second.

I generally don’t like alien invasion plot lines because in most of them there doesn’t seem to be a reason for the aliens to invade Earth. But with Colony there seemed to be a reason for the invasion, it just wasn’t quite revealed. To conscript humans to be soldiers to fight against some other alien race… I guess? They really left us hanging there.

Jericho would’ve been worse, but at least they made a mini-series to explain things and give an ending. Well and open-ended kind of ending, but we can kind of imagine how the rest of the story would go. With Colony, we didn’t get that.
