Holy heck this was a tough watch. And quite a bizarre one too I have to say. On the one hand you have a lame duck of a horror movie with almost nothing to offer, yet amongst all that you have the natural charisma of Nick Frost doing everything it can to shine through. Could he do enough to save it? He could not.
This movie just didn't work on any level. It wasn't intriguing, it wasn't scary or mysterious or tense. It was just a nothing ride. And frankly quite an unpleasant one too. All the characters were highly detestable people and not a lot of fun to spend 90 minutes with.
For whatever reason the British do not seem to do horror all that well. I've seen very few British horror movies over the years that I've actually enjoyed and 'Black Cab' was certainly not one of them. 4/10.
