I say after the Vong Invasion it should have stopped, we should have seen some more optimistic stories about them from that point forward. I really feel the EU betrayed the tone and premise of the whole big 3 era kicked off by the movies by pushing all the family drama and turmoil for these characters after the Vong Invasion. Anyone who feels this way but has a different cutoff point in the chronology for the grimdarkness?
Or has a disagreement about something else...
