The movie appears to have set aside the fact that each time Sakura has sex with Shirou, it is slowly killing him.
Aniplex USA has, naturally, picked up the movies and screened the first film in U.S. presage flower, was released on October 14, 2017. The first film, titled Fate/stay night: Heaven's Feel I.
The first preview can be viewed here, the second preview here and third preview here. Although the films never get as graphic as the visual novel in this respect, they don't shy away from showing it either. However, Shirou and Sakura's relationship has a strong sexual component that is much more central to both the plot and their character development, so it would have been much more difficult to adapt out. This also applies to the sexual content (particularly in the second movie), which in previous adaptations was infamously tip-toed around, partly because in previous routes, the sex scenes were a bit tacked-on due to the visual novel having originally been an eroge. And since, this being a movie, the creators didn't have to hold back on the graphic material like in previous adaptations, you can also expect those deaths to NOT be pretty and the movie to show every excruciating detail. Expect Anyone Can Die, even for characters who seemed to have Plot Armor in previous routes. The story of Heaven's Feel is, by far, the darkest in all of Fate/stay night, both in tone, themes and imagery, being often akin to a horror story. In this situation, Shirou will have to choose between upholding his ideal of "Hero of Justice who can save everyone" and his desire to protect the girl he loves over everything else. This time, the story focuses on Shirou's budding romance with his junior schoolmate Sakura Matou, but in the process, he uncovers a dark secret about her and her family that threatens to destroy the world. This trilogy presents an alternate take on the Fifth Holy Grail War from that seen in Fate/stay night. From there on, the story completely deviates from what was seen in the previous two routes. He also forms an alliance with fellow classmate and secret mage Rin Tohsaka, who also participates in the war, and her mysterious servant, Archer. Ten years later, the Fifth Holy Grail War starts, and Shirou, now in his late teens, gets dragged into the conflict by accident, including inadvertently summoning his own servant: Saber, the same servant who served his own father in the previous war.
