Did you loose interest before SGU's cancellation? For me, the Atlantis series finale ("Enemy at the Gate") was the last great Stargate adventure. Sure, we got 40 episodes of SGU before it all came to an end, but it just wasn't the same. I tried to watch SGU, but I lost interest after "Air, Part 3." Atlantis flying back to Earth to fight off a Wraith hive and save the Earth for once instead of SG-1 was a nice adventure to end Stargate on.
