To me, it definitely felt like they were combining a lot of the main elements of 24, Lost,
and Heroes. The government conspriacy and clock elements (heck, even the text font) seem straight out of 24. The flashback style plotting is reminiscent of Lost, and the prison where Sophia's "people" are kept seems very heroes-esque, although aliens, demons, vampires, or angels could easily be another explanation. Not that I'm complaining about these being necessarily derivative, but about fifteen times in the episode I thought "Oh, this is just like show XXX did it," and that's about fourteen times too many. The climax also seemed a little underwhelming given all the buildup they had for it. I'll get over it if the show's good, but first impressions are OK at best.
