I had to look up what were the 3rd and 4th Season about. They were so not memorable. The Alien part was the best part of this show, they should have developed it further instead of kill it off and come up with this political drama in space for the last 3 seasons.
I thought Season 3 was the "grand finale" of the protomolecule storyline? Maybe I'm remembering things wrong. Some of the side-stories and disposable characters of that "finale" season fell flat on me, but it also had some of my favorite episodes. But like I said, maybe I'm remembering wrong and it's Season 2 I'm thinking of..
While I've lost my enthusiasm for the show, I'll still watch Season 6 since it's the last one. I'm not necessarily looking forward to it, but I might as well ride this train to its destination, having come this far. Maybe I'll play ED while watching this in the background - a game so boring we have to watch TV to pass the time, and a show so boring we have to play a game to pass the time - a perfect marriage, LOL
