Really enjoyed this, I think if you liked The Big Short (same director Adam McKay) it'll please most folk. It's not a total assassination of Cheney or the Bush Whitehouse. Great cast.
It has Will Ferrell (worked with McKay on Anchorman) listed as one of the main producers I hope he keeps producing because he's not funny.
I prefer the US artwork (the UK artwork looks like it belongs in Poundland):
