Spin-off series with a lot of potential. but the series is filled with disappointing episodes that feel like rehashes of other shows and series and some of the fillers (especially in it's first year) stink. Too many episodes also rely on either a crew member getting kidnapped, getting a strange virus or being trapped with a big problem to solve (or all Three situations combined). The main villains were memorable as they could suck the life energy out of humanoids but their looks was terrible as they looked like old tired Goth rockers who had been travelling a little too long on the tour bus. It also didn't help that they became more and more humanized after the series went on. My biggest problem with the series though was David Hewlett who were terribly annoying throughout and Joe Flanagan who felt like a poor-man's Richard Dean Anderson or Kurt Russell. The season-enders and beginnings were usually the most interesting episodes to see as they were filled with action and great effects. The series were also not afraid of killing off favorite (and not so favorite) characters permanently. The series usually got some great new additions to the cast too for each season, with Jason Momoa, (the lovely) Jewel Staite and the addition of "Stargate SG-1" regulars was lovely. Sadly, the final episode was anti-climatic and the fate of the show has never truly been resolved. Enjoy it for what it is.
