This is the worst anime I have ever seen. The story was all over the place. They tried to do something with turning the Holy Grail War into an RPG style virtual dungeon game (where they fight the main boss of a floor and then proceed to the next). This is a cool idea but they hardly explore it at all. The characters were generic and boring, none of which having the potential to go much deeper except for Saber/Nero. And Nero is supposed to be the character that "carries the show", but honestly I found her to be passable at best. There are hardly any fights (which was what made me fall in love with the Fate series in the first place) and the one's that are there are boring and lack creativity.
There were times when the show attempted to present deeper philosophical themes, but those were mostly ill timed in the context of the scene and just felt out of place.
The sound design and visuals were passable, but nothing in particular really stuck out to me.
I never thought I'd find the anime that dethroned Sword Art Online as my least favorite, but I think I can sum it up like this:
A cringey show is better than a boring one.
