In the first season of 2005's Doctor Who, viewers were introduced to Capt. Jack Harkness (John Barrowman), a 51st-century time-traveler, con man, and charming rogue. His character proved so popular that Who producer Russell T. Davies launched a 2006 spin-off, Torchwood. After changing his ways because of his encounter with the Doctor, Jack now leads a covert operational group in Cardiff, Wales, known as Torchwood, which is tasked with tracking down alien life on Earth. Considered "outside the government" and "beyond the police," his team includes: Gwen Cooper (Eve Myles), a Cardiff police officer; Owen Harper (Burn Gorman), a medical doctor; Toshiko Sato (Naoko Mori), a communications and technology expert; and Ianto Jones (Gareth David-Lloyd), the group's assistant. Torchwood's increased violence and sexual content (often focusing on pansexual Capt. Jack) sets it apart from its predecessor, and that's a good thing. It allows the series to place more focus on the complex adult relationships within the team dynamic, rather than focusing on rampaging aliens week to week. Most episodes have more to do with alien technology and the effects it can have than with actual creatures, anyway. But don't get us wrong -- seeing the team outsmart fantastic computer-generated monsters is a definite highlight on this sci-fi series. The 13 episodes of Torchwood's Season 1 originally aired on the BBC in the U. K. and made it to cable network BBC America in 2007.
