You will wonder what level of hell you've wandered into when you first start watching this. The acting is dire. The editing is terrible. There are so many utterly baffling decisions made that you will find it very hard to sympathise with anyone at all. But, hang on...the last 10 minutes suddenly makes it all (almost) worth it, and with the benefit of hindsight you'll find yourself going...ohhhh...NOW I see... 6 stars because it's actually not awful and the ending is actually quite surprising and a little heartbreaking.
