Great concept executed so well. I loved this from the moment it started and I only paused once to eat and shower. It would have got 10 stars if it wasn't for one of my pet dislikes, a bizarre London accent. Karl Urban's weird Kiwi/London accent made me cringe with every line he uttered. He joins Johnny Depp, Elijah Wood, Don Cheedle and, Charlie Hunnam in my London accent hall of shame.
