Tonight in HD: February 6

SoHo Highlight: Hell on Wheels (Sky 10, 5.15, 5.1) If you missed Sunday’s screening, catch up with this repeat, in which Cullen’s search for the sergeant is unexpectedly diverted and Durant organises a search party for Lily Bell (Dominique McElligott, above). “Choo-choo!” exclaimed New York magazine at this stage of the series. “We’re three episodes into Hell on Wheels and things are finally starting to move. Characters are developing, motives are becoming clear, and, for me at least, expectations are lowering, making A Birth of Freedoms easier to enjoy than the last two episodes. It just takes a willingness to stop rolling your eyes at Doc Durant’s over-the-top bloviating and Cullen Bohannon’s never-ending list of cowboy superpowers and accept them as quirks of a show that as much as we want it to be, just isn’t Deadwood. I’m there.” ✭✭✭
