My son had wanted to watch this in the cinema and was annoyed that I would not take him, someone under the age of eighteen, to watch this, a film for those over the age. After watching this at home, I would have been okay to watch it in there, though of course, not with him as it would not be legal to do so.
The film starts well and I think it builds up to the final quite well. I cannot compare it to the films it will be compared to without giving away the plot, but it was quite good and I could not watch the final scene, which is a reflection of how good a film it was. The Guardian rated it four out of five, and I would have to agree with that. I am not sure that I will watch it again though.
