That was very good! It had a lot of action and a cool premise (vaguely Hunger Games like, though contests like this predate Hunger Games and Fate/Zero, and of Course Fate came before the Hunger Games).
It was full of interesting themes such as Human Nature, the danger of playing God, etc.
I think the best part for me though was to realize that I was not the only one who thought Saber was Joan of Arc. xD
That Bluebeard insane guy did as well... I guess I'm not in the best company then, haha.
