Which proves that it's the producers and not the SG:U concept that are dragging everything down. When Jonathan Glassner left SG-1 way back in the olden days, that was when it all started to slide downhill.
You think the peak of the franchise was before season 3 of SG-1? I don't think many fans would agree with you.
After Glassner left, it seemed like a lot of the heart went out of the series, leaving just a lot of empty action. But without heart, action is pointless. For a while, they coasted along with some fairly competent action, which was watchable in a mindless way, but I definitely noticed the difference. Then, a few seasons on, even the action became repetitive and increasingly unbearable.
Whether or not "fans" agree with me is immaterial. Glassner was the only person who was keeping SG-1 from turning into a generic space opera action without any particular identity. Even when he was on board the show wasn't all that good.
None of those characters really interested me all that much. Ba'al at least wasn't another cardboard Goa'uld and the episode with Janet's death was interesting, but that's pretty skimpy. Martouf, like all Tok'ra, never went anywhere interesting. I watched SG-1 for years, "waiting for it to get good." All it ever achieved was a barely tolerable level of watchability.Thor, Harry Maybourne, Ba'al, Matouf, Jacob Carter, Janet Fraiser, Bra'tac and Oma Desala.
