Children of Earth is probably RTD's masterpiece, but I must admit to loving the whole show way, way too much. S1 is very bleak (and the weakest overall) and S2 is more upbeat and fun (and both of them fabulously crack-tastic), but it doesn't have as much sex in it as everyone keeps saying. It's more that the attitude of the show reflect its leading man, but it never made me uncomfortable, and I'm not really one for sex-scenes.
