I don't usually review any movies. I don't particularly like British movies or Tv shows due to the fact that I have trouble understanding their speech. I did have the problem with this movie as well. I turned on the closed captions to help me understand.
I enjoyed the movie immensely and the acting was as good as any I've seen before. The movie is painful to watch at times due to the brutal fighting and also the strained relationship of the main character and his father.(Also a prisoner at the same prison.) The scenes when the two are interacting are touching and sad. The only thing that I was dissatisfied with was the ending which was a big disappointment.
