I personally felt that Stargate: Atlantis should have gone on for 2 more seasons. They had enough material and I liked the cast and they way they played off each other.
The feel of STG1 and Atlantis is drama with comic elements and it works well. Universe on the other had deparately needs that comic elements. I think the highlight of the show so far was seeing Colonel Young go postal and leave the creepy scientist stranded on the one planet. Then that female beareaucrat sucked all the fun of that. Maybe next time Colonel Young can leave both those characters on a planet.
It's hard to get into a show when you only like one character and that is Eli.
Hopefully, Sanctuary has gotten better.
