Life on Mars: Season 2. Episode 6

 "Yeah, they come over here, they take our bullets..."

It's no coincidence, I think, that Life on Mars leaves it until so close to the end to do a big, full-fat racism episode, full of casual bigotry from Gene and the gang. This is the one thing where, even given the 1973 context, in a 2007 programme we need to know the characters well to accept this kind of thing. In the end, though, the whole subject is dealt with sensitively and well, and even with some romantic musing over music, exile and the contemorary plight of Ugandan Asians, one year after Idi Amin expelled them. It would have sat better, I think, from a South Asian writer, but Guy Jenkin does a good job.

Gene and Ray keep the casual racism flying to Sam's dismay, as the temporal culture clash reaches its peak here. This is good character stuff for Sam but nicely balanced in not going too far with Gene.

It's also the wittiest episode for a while, with Gene in particular getting some superb lines. After it seems they've used up all the coma-related 2006 plot points we get a good one as, this time, Maya slowly decides to give up on Sam- just as the plot concerns her rather groovy parents. It also works well as a whodunit that doesn't cheat, and even develops Gene by giving him a brother addicted to speed. It also has the finest ferret scene I've yet to see on television, and Sam getting to interrogate his girlfriend's father.

It's a standout episode, again not written by a showrunner. It's also, I suspect, our last one-off whodunit as the end approaches...
