Released 2017 and 2019, respectively
Prerequisite: Fate/stay night original series and/or Unlimited Blade Works or other familiarity with the franchise prologue.
Strongly recommended: Fate/Zero.
The Heaven’s Feel movies offer no recap of the events that start the story, including the initial attack and introduction of Saber, other than a brief montage in presage flower that’s more artistically evocative than explanatory. It is assumed that you have seen it all before, and will make no sense if you haven’t.
Heaven’s Feel is Sakura’s route. We had a glimpse of Sakura’s traumatic childhood in Fate/Zero, and her story definitely needed to be told. Unfortunately, Sakura’s quiet personality makes her kind of weak as a main character.
As expected, these films (parts I & II of a trilogy) are stunningly gorgeous, the best-looking rendition of Fate/stay night yet. While presage flower provides some set-up, lost butterfly features extended battle action scenes. By the end, a lot of troubling revelations come to light. I’m definitely looking forward to the final film, although I don’t really see how this can end well.
