Good effort trying to reason with the Fate/Zero fanboys, but unfortunately they're not going to see beyond their own bias. Fate/Zero has been a narrative failure, with amazing characters with a poorly written plot - at least in the anime adaption.
I still gave it a 7/10, because everything apart from the pacing was excellently done.
Perhaps I would have thought differently if there wasn't a break between cours. As a result I was expecting at least a conclusion to some things in episode 13.
Only good thing I can say about F/Z ep 13 is that I think I've found a yaoi couple I can genuinely ship - Rider and Waver.
