Very good - but you might need subtitles Fassbender is a good actor as is Brendan Gleeson and the story is a good one.
It is hard to understand what they say & i am Scottish!! It's all gypo ( gypsie) talk and anyone from anywhere else other than the UK is going to have a hard time with this - subtitles needed :)
The story is a well trodden one - where the main character wants to change his life but is enmeshed in the culture he was brought up in and it's taking him down.
Some good car chases - even through fields!! Someone said it has no redeeming qualities but ultimately it's not Hollywood and there are no happy endings. A good gritty story with tension and a fair bit of action - food character study - Fassbender does a good job here.
