This felt kind of like the film Children of Men, except this was good. A similar setup - with endless rain in Britain, the rich live in luxurious domes and the poor out in the rain and mud - but in this case it turns out that the conspiracies exist for a reason, not just because the story requires it.
The hero is a cop who stumbles onto something he shouldn't, and he's a classic action movie hero. Specifically, he's from the 'take continual beatings and keep going' mold (e.g. John McClane).
