Eureka returns in July, something we tend to expect these days. But this time it comes in on Friday nights instead of Tuesdays, joining the strong tradition of ScfFi Friday shows like Battlestart Galactica, various Stargate incarnations, Doctor Who, Primeval, and more. It also coincides with their branding switch to SyFy, so all we need to round it out is the new Riverworld TV series they commissioned. While over at BBC America, Ashes to Ashes hits its season 1 finale tomorrow night, with season two kicking off the following Saturday. New episodes of Primeval and Torchwood are coming soon, as well as another original series, Being Human.
