Good movie with a terrible ending

Rating: 5/10 (31 May 2016)

Haven't written a review before, but just had to write about this movie.
A friend recommended it as a great movie, I wasn't so sure in the beginning. Half way through the movie it seemed it's really gonna be quite good. The casting has been great, the characters are played well, they are believable. I really looked forward to what's gonna happen. I had no idea, I hadn't read the reviews.
And then came the ending... seriously?? Thought quite a few better ways to end this movie...
Would have been 8-9/10, but the ending was really disappointing.
