Beasts of No Nation. It's one of those Netflix original jobbies so I don't think had a cinema release but it's well worth a watch if you're on t'flix and like your films bleak. The plot follows a young boy in an unnamed West African country who loses his family in a civil war and joins a child soldier militia, headed by Idris Elba's character, the "commandant". A very tough watch and not one for the nippers though.
