Have you seen Dawn of the Deep Soul yet? I watched it last month and it is, in one word, SUBARASHII!
I know quite several people super into Fate but I ever really got into it myself. I gave the first four episodes of Zero a go but kinda lost interest, I have been meaning to go back to it though at some point, because I don't recall thinking it was bad. Worried at this point I'd just have to watch it from the beginning again and the first episode was like an hour iirc.
Both Violet Evergarden and Tanya are both series I want to check out though, especially Violet Evergarden. The trailers made it look like the prettiest show ever.
