Although it has its amusing moments, in eneral the plot does not convince.

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

This movie feels like it was made purely to piss off people who want good shows

The film never slows down or bores, plunging from one harrowing sequence to the next.

John Moody drives around Britain's cities in a Black Cab picking up customers. While this may sound like an interesting idea for a docu-soap type programme, this is not the end of the story.Cash Cab is a gameshow. When the unwitting contestants step into the cab, thinking they're about to fork out a tenner for a trip down the road, they are instead greeted by flashing lights, screaming sirens and quizmaster come taxi driver John Moody. He explains to them the simple concept: He asks them questions, they get money for getting them right. Get three wrong before they reach their destination and they get booted out, win no money; but they don't have to pay the fare, so that's nice. If they get to their destination without losing all their lives they leave the cab with a healthy wad of cash, smiles on their faces, and a 15 minute stint on one of the most original and quirky gameshows in a long time.
