Absolutely amazing.

An enthralling battle of wills and morales among twelve men of vastly differing principles, personalities, backgrounds and intelligence; all done within one room for the staggering majority. What you see is what you get with this film: a crowd of strangers at odds with one another over an initially “open and shut” case of first degree murder. It’s mental and verbal warfare; the film is completely portrayed through dialogue and character behaviour. I don’t want to say much else, just please watch it. 

9/10.
