My copy arrive this week, so gave it a watch last night for the first time. Overall very enjoyable, found my attention slipping towards the end of the second act, but once the 'Othello' scene cropped up my interested was drawn right back. One of the best 'what the f*ck' moments I've seen in a film for some time.
The blu-ray is lovely all round however, as you would expect from Camera Obscura.
