SERIES PREMIERE: This new CW premiere is another in the network’s series of sci-fi fantasies populated by impossibly beautiful and handsome young adults. You may consider this one worth sampling, at least once, though, for two reasons. One is the far-fetched premise, which has a space-station colony that has orbited a nuclear-war-ravaged Earth for almost a century, and is sending down youthful prisoners – led by Eliza Taylor as Abby – as test subjects to see if the planet is ready for repopulation. Hey presto, kids!: It’s part Dirty Dozen, part Lord of the Flies, part Survivor and part The Time Machine. But the other reason to watch is that the space station folks, the ones in charge, are a bit older, wiser and more talented than the usual CW crowd. They include (pictured) Henry Ian Cusick, who played Desmond on Lost; Paige Turco from Damages and American Gothic; and Isaiah Washington from Grey’s Anatomy. Parts of the premiere are absurd, but there are a few unexpected moments, too, which is a step up for the CW.
