You've got to wonder if Dr. Nicholas Rush (Robert Carlyle), the single-minded genius on Syfy's SGU: Stargate Universe, is on the right show. Maybe he hopped over from Caprica before anyone noticed and now it's too late. However it happened, Carlyle's character is so morally ambiguous we don't know if we can trust him. Looking at his deeds just in the six episodes that have aired so far, you really have to wonder: Is he evil? Maybe not evil like Darth Vader or the Master, but evil like Battlestar Galactica's Gaius Baltar or Lost's Ben.
