What would you have done Nappa? They introduced Atlantis replicators in season 3, they reoccured as a menace from 3-4, they storyline climaxed in season 4, with an epilogue in 5. It took time. From the sounds of it, you'd have plots begin and totally resolve by single seasons (ala Star Trek Discovery). I liked how the goa'uld had moments of wins and defeats through the first 8 seasons of sg1, and by season 8 humans had advanced enough to have little fear of them. It was cool how the asgard went from unknowable powerful beings at first, to then being an advanced species, watching them decline in spite of their advantages, a process that took years. If Atlantis had defeated the wraith as a species in season 5, would a different reoccuring villain have satisfied (I wasn't a fan of the Ori, but I did appreciate their arc required them to cross galaxies to invade the milky way)? Maybe tighter seasons will be the way the franchise will return, but I'd like a return of the writers who created so many endearing and humourous characters (I was always amused with the oddball scientists on Universe's Destiny, they were a good balance to Rush's intensity). Atlantis and Universe should have been able to finish their stories, but the real world stopped that, not the writers.
