The main character kills her kitten with a knife. The cat is off-screen but we see it's blood and the next scene shows the cat's dead body being buried. To skip, go to 50:30 as soon as she grabs a knife.
(Spoilers) MC considers gifting a cursed object that will kill the owner to a man who is disabled and on oxygen out of a group of people at a diner, seemingly because he has less of a life to live.
In an photo that is supposed to depict what the main character looked like as a child ("former fat kid", as someone in the film remarked) it is very obvious the child actor (with the character's adult face terribly photoshopped onto it) is wearing some type of padding around the stomach or is similarly poorly edited to have an awkward midsection that looks anything but natural.
SPOILER FOR ENDING:
The main character is dragged down to hell despite her trying to escape this fate throughout the whole movie, her boyfriend (whom was about to propose to her) watches in horror as this happens right in front of him
