I just watched this movie for the first time. Loved it. I'm a incomplete C3 tetraplegic following a motorbike accident, so I can move a bit. Just not much. Obviously I know it's fiction but if somebody offered me that upgrade, I'd bite their arm off and give them everything I've got or do whatever they wanted in return. I mean - literally- anything at all. It's almost every cripple's dream and I wish to God it was real. Anyway, I enjoyed the movie.
