Always the wraith

I might say more about Stargate Atlantis sometime, but for now, I just want to say how simple the plots seem to be. I'm surprised the show has been running for a while because sci-fi audiences tend to be more critical. I'm not into sci-fi enough to go to message boards and websites to see what fans are saying, so maybe I'm not the only one who sees it, but it seems like Atlantis plots are always about the Wraith attacking Atlantis and other planets in that sector.

Plus, there doesn't seem to be much mythology or back-story to the show, so there's not much depth. There are some shows that have described certain cultures in that part of the galaxy, but not enough. It's often, "Oh no, the Wraith are coming," or "Look at this--the Wraith were here," or "We're trying to avoid and/or defeat the Wraith."

Basically, I don't go out of my way to watch the show, and if it's on, I often eventually do other stuff and keep it on in the background because their plots aren't very complex or gripping enough.
