Have seen the play which was excellent i hope the film is as good. I would think anyone who has an interest in equines and the part they have played in in mans development would be interested you need to know the good and the bad to learn. I read a book regards how men in the first war became so attached to their horses and the hellish things they had to endure they could not bare to be parted. Sad thing is that after the war for the horses that survived the only thing they got was slaughtered for meat. The point i am trying to make is that all through history man has used and abused the best friend he ever had and but for the horse we would probably still be living in caves.
