This is a very uncommon, unusual, offbeat and unforgettable experience for any movie goer. Claustrophobic, not for all audiences - my wife left the room whilst she watched it mith me, accusing me to hurt her - but I persist and sign this is a masterpiece for many reasons. Directing, settings, acting, rythm, editing, everything, every scene is tense, taut, sharp as a razor blade. Yes, it is disturbing, not recommended, if you are depressed, and if you have suicidal tendencies. You can't miss this rare gem, diamond, chiseled diamond gem from Hollywood vaults. Nasty at the most, it could be considered as a guilty pleasure for masochistic reasons.
