Stargate Atlantis Second Season

If Stargate Atlantis isn't the coolest sci-fi series on television, this five-disc, 20-episode box set from the second season (2005-06) offers ample evidence that it's right up there. The writing is good; the stories are intriguing, and the science part of the equation is credible enough to justify our suspension of disbelief. The characters are for the most part well-defined, and the acting, while perhaps not Emmy-caliber, is just fine. The action is exciting, the effects work impressive, the costumes and sets first-rate. But what Atlantis really has going for it is the presence of some of the baddest bad guys in the cosmos: the Wraith.
