I couldn't stand the seasons of SG1 after O'Neall left. First, I had a major problem that after eight years of barely saving the planet from destruction because you went out too far and pissed off an ancient power they weren't ready for, they did the exact same thing again. Also Browder was wooden as hell, Vala was over the top and lacked believability and felt shoehorned into the team. From that point on, they just repeated the pattern of "We need to find this ancient artifact or we all die!" they repeated since season 6.
