- Augustus Waters dying.
Hazel: The only person I really wanted to talk to about Augustus Waters's death was Augustus Waters.
- "The beautiful couple is beautiful".
- "Gus, my love, I cannot tell you how thankful I am for our little infinity." The entire scene at Augustus's prefuneral, really.
- Augustus' breakdown in the gas station parking lot.
- The flashback scene where a younger hazel lies in hospital and her parents think that she is dying now
- Hazel's mom. "I will always be your mom, Hazel."
- The above counts more for happy tears. The line that leads up to it, much earlier, "I won't be a mother anymore." is one of the most powerful lines in the book.
- I do.
- Even more emotionally jarring when you consider how well Augustus knew Hazel. He was most probably expecting and hoping for that exact response to invoke the "spiritual marriage".
- The song that plays in the film version of that scene counts as well, courtesy of M83. It's very moving.
- Caroline's story.
- The reason Peter van Houten is such a drunken ass. His daughter died of leukemia, which is what inspired him to write An Imperial Affliction. Hazel reminds him much of his daughter, which is probably why he treats her like shit; it's too painful for him.
- "It would be a privilege to have my heart broken by you, Hazel Grace." Especially when you realize at that point, he knows he's dying. He's saying it would be a privilege to live that long.
- The first trailer for The Film of the Book. The shot of Hazel's mom running into Hazel's room while Hazel lays there screaming in pain on her bed really hits, hard.
- Peter van Houten, after exiting Hazel's car, looks at her for a moment, glances at the flask of whisky in his hand, and just for a moment, you think he'll leave it behind. And then he doesn’t.
- To Esther Earl.
- The song "All of the stars" by Ed Sheeran at the credits. You were literally leaving the theatres crying.
- The aforementioned song from the final scene. It's the penultimate tearjerker of the film.
- The death of Augustus in the movie. It's announced by narration. Hazel is in bed, and hears the phone ring from downstairs. The look on her face says that she instantly knows what's happened, and she tries to pretend to be asleep when her parents come into the room. It's almost as if she's hoping that she can avoid facing it by pretending. But when they give it to her, she collapses sobbing into the bed.
- The scene doesn't end there. Hazel keeps crying into the bed for a whole minute afterwards. Shailene Woodley's voice is a Most Wonderful Sound for many. So hearing such pain and anguish in it is heart-wrenching.
Tear Jerker / The Fault in Our Stars
A Twitter user called The Fault In Our Stars "a book that you could literally throw at someone and it wouldn't hurt nearly as much as the story did", and for good reason.
