Honestly, I started this purely for completions sake expecting nothing more than laughs and cuteness, but by the end this brought home the core themes of Fate and left me with a full heart. It's genuinely informative and will give you a greater understanding of the characters in Zero and the confusing world of the Holy Grail War while making you laugh. I'd say it definitely set the bar way higher than I'd expect for a box set special and I'd recommend it wholeheartedly for any Fate fan. Also that twist at the end blew my mind.... don't spoil it for yourself, just watch it.
