Haven't seen it and not sure I could watch it having damaged my right arm so badly that it nearly cut my hand off completely.
I have a pretty good idea what it's like to get through the skin, muscles, tendons, arteries and nerves, didn't quite cut through the bones just fractured them, remembering it is making me wince just writing this...
That was 29 years ago and I still have no feeling in that hand and due to restricted blood flow it's always freezing cold. [shudders]
I don't remember as I was in shock, but I was told that I lost pretty much half of my blood in the time in took the ambulance to get there and all they could do was wrap it in bandages, so many that it looked like a small rugby ball in the end, I almost died from that but after a month or so at East Grinstead, nine months in plaster and 2 years learning to use a hand I can't feel it's all good.
I certainly wouldn't be blasé about having to cut my arm off to survive, mine was an accident, to actually cut it off yourself...
Ah sod it, I'll grab it and have a watch later on as I can't really comment on what he should or shouldn't have done without seeing it, apart from the fact that the human arm is a tough beast to get through.
