The Film "Stargate" from 1994 introduced the idea of a device that allowed people to travel from Earth to other planets. This was such an interesting concept that it lead to the development of the "Stargate SG1" TV series which used the same characters, if not the same actors, to expand on the original theme. After 7 years, a new franchise "Stargate Atlantis" was developed.
This is the first season of that storyline and the action moves further out into the universe, with most of it taking place in a different galaxy. The members of the expedition team are rather more on their own than those of the original series, so the dynamics of the storylines are slightly different. There is still a vicious alien race that are the bad guys, and other humans that the Stargate teams are trying to protect.
There is slightly more tension between the various people than in SG1 as the team members are composed of fewer military personel and more scientists. The episodes often have a slightly "grittier" feel to them, and less of the comedy that was a feature of SG1. The extras on the disks are also very useful in showing how the episodes were created.
If I was being very critical about the box set, I think that it's rather odd that they don't include an episode list; something that I would have thought to be essential. However, I suppose that I can create my own and put it in the box for reference.
Suitable for a present for many people (I would have loved to get this as a present) or if you are an SF fan.
