Originally, Stargate was a show with open ended possibilities. You had doorways to an *unlimited* number of worlds and the possibility of occasionally peppering a season with the sci-fi wet dream of temporal malfunctions. Create a team of four people with unique personalities that most viewers could relate to, toss in some humour and we had an enjoyable, adventurous romp through space that started and ended with practically every episode. How can you go wrong!? How can you not have 10 seasons of fun!?
Fast forward a few years and we take that formula, add in an overarching story line with an evil warring race, maybe a few extra characters to the team and, while it's not the same, it's still pretty damned good.
Fast forward a few more years and we take the mythos, remove the humour, and apply what we'd seen in the successful Battlestar Galactica franchise minus the deadly yet cool robots, and we have... a cancellation.
It seemed as though we were moving in a decent direction at the end of the most recent season, where they were finally gaining control of the ship and moving in a Star Trek Voyager direction but maybe it's too little, too late. Where's the sci-fi? Where's the space exploration? They're in deep space for crying out loud, why aren't they encountering bizarre worlds with amazing effects, aliens with odd customs and why are they continually engaging in human drama. How many episodes of Rush friction do we have to deal with?
