If you like sci-fi TV shows, I have a recommendation: Life on Mars, a British show that debuted in the U.S. this week on BBC America. The premiere repeats this Sunday night at 9:00 p.m. and again at midnight. It’s about a Manchester detective in 2006 who’s in the middle of trying to solve a crime when he gets hit by a car and is suddenly transported back to 1973. He has no idea how he got there or why; even weirder, he can’t tell whether everything around him is real or whether he’s just in a coma and imagining everything. It’s really eerie and unusually emotionally resonant. I watched the first episode the other day and I highly recommend it.
