Quite frankly, unless these new Super Aliens are there to help, the last scene with the whole crew standing in a crowd, rifles and pitchforks at the ready and in a perfect position to be wiped out in one large explosion, would have been a satisfactory ending for the series. I don't know if i'll continue to follow for a 3rd. The confrontation at the end, with the rebels coming to the rescue, was pretty well done.
