A look at tonight's sci-fi TV:
Dollhouse, "The Public Eye/"The Left Hand" - Dollhouse is officially done for, but Fox still has a few episodes left to air, including tonight's tense-looking two-parter. Echo is sent to dispatch Senator Perrin (Angel's Alexis Denisof) before he can expose the Dollhouse, while Adelle and Topher meet up with genius programmer Bennett (Summer Glau) at the D.C. House. Later in the ep, Adelle clashes with the another Rossum head honcho (the always brilliant Ray Wise) while Bennett plays mind games with Echo. Elsewhere, November finally goes public with what she knows, spurring Topher to experiment with some cool doll "disruptor" tech. Let's hope tonight kicks off a string of great final episodes that will leave us wanting to send those impatient Fox execs to the attic. (8 p.m. on Fox)
Stargate Universe, "Justice" – Tonight's mid season finale is packed with big developments. Someone aboard the Destiny is murdered with a gun found in – gasp! – Col. Young's quarters. Did the weasly Telford somehow sneak aboard to frame the good colonel, or is there something even more distressing going on? (9 p.m. on Syfy)
Sanctuary, "Next Tuesday" – Will and Magnus spend the episode swimming in sea creature-infested waters after their helicopter crash lands on a decommissioned oil rig. And Will screams, a lot. (10 p.m. on Syfy)
