|Life on Mars is where good coppers go when they die. Everybody gets a different one. Gene Hunt's like St Peter, or God or something. Makes perfect sense to me.|
I think so, yeah.
Sam, I suppose, being the kind of character who'd have joined the Force so he could 'make a difference', while at the same time having signed up for duty because he was on some level seduced by images of early Seventies cop shows on TV.
So '1973' is really the best, most comfortable version of hell, or the Bardo experience, anyway, that's available to him. It's a bit tragic to think of Sam fighting with Gene's unreconstructed ideas for the rest of enternity, but on the other hand, from Sam's point of view, he does get to make a difference, plus get in car chases and so on, so it could be worse.
It'd be a bit crass to bring up 'The Third Policeman', but as an example of a hell that would, in a funny way, be almost tolerable, it's possibly, vaguely, something that was being referenced in the script.
