This is a film that is made for Type-Moon x ufotable fans through and through. You will especially get a lot of out of this film if you have already read the visual novels and have seen all the previous main Fate franchise anime. Ironically, the core hook of this film is its story and characters, which I didn't think was going to be the case because I just simply didn't think they would go in such depth in exploring the themes and characters in a humanistic way.
