Is R.I.P.D. a kind of extreme Ghostbusters reboot? It's almost the same premise, except instead of being a small group of underdogs trying to catch ghosts in the open, it's a massive supernatural organisation catching ghosts in secret. So, a bit, maybe, I guess? When I see it, I'll let you know, if I remember.

PS - I also see shades of "Dead Like Me".
PPS - Which, in turn, was a loose adaptation of Piers Anthony's "On A Pale Horse".
