Worst. Ending. Ever.
...And the producers knew it - desperately explaining it was based on a historical event (or at least a revered story) at the end. Not only did they swiftly explain it via narration, but also, put up titles before the credits ran!
As for the sole survivor who the fat, bald poofter in gold ALLOWED to live - I don't think he'd further his father's bloodline - he was clearly a woolly-woofter himself!
Just kill the golden, bald bully and all his men and run titles. Fixed! 5/10.
