So bad, it merits one of my very few reviews.
First of all, there's barely explanation for the actions and behaviours of the characters. Things just 'happen, and you're left wondering if you somehow missed 5 minutes of the film, but no, it's just a really bad script and awful directing.
I am not British, but I lived there a long time, and the girls accent, doesn't sound quite right.
I couldn't finish the film, as one of the last scenes is beyond cringeworthy, and had to turn it off.
Awful. The good reviews must have been paid for, as usual.
