Totally Cam, it felt like they pushed the story too much out of its boundaries.
Although the final villain was a change of pace, it was underplayed... but at that point I only wanted the season to end, it had already dragged itself too much.
And yeah, about those leaving... damn, it got me all emotional. Although I agree with the new leader's choice.
Let's hope for the next season, and enough of sci-fy crap.
