Michael Harrington MP is discouraged with the state of politics and spin and is a pretty convincing character with a nice turn around from selling the party line to airing his true feelings. Sadie the lead character is perfect for the worn out sister health carer role with some pretty solid acting. Multiple aerial shots break up the scenes and don't really get repetitive, adding some good transitions. The Whip himself is a classic bad guy but not too much of an archetype but we recognize him to be the villain pretty quickly without any unnecessary exposition.
The story focuses pretty heavily on social inequality and the bad guy politicians are obviously the Conservatives (since they'd been in power the past decade or more) but the film doesn't overtly turn into a social action flick and stays along the Oceans 11 style heist.
The heist team of 4 occasionally seems a bit small (don't expect Oceans 12 or 13) and their planning room does seem a bit bare as we'd expect to see a lot more maps and notes to give the feel of a heist in planning but the acting carries the story over these minor bumps.
Into the actual heist the action moves along pretty quickly and while locations and sets are occasionally sparse (ok it's actually not possible to film inside Parliament!) it's hard to worry about it for long since the heist moves along at a swift pace along with a few good twists and turns.
Overall The Whip is an enjoyable film with a solid cast performance and a story that is just as believable (suspension of disbelief) as Danny Ocean and his crew.
