Some people might read the dad's overbearingness and drive to push her quite abusive, but there is no physical abuse shown. There are verbal scenes of him coaching her in a very aggressive manner which could be triggering.
For once- there is a woman in a bathing suit and wet clothes the whole movie and she's never once sexualized... great job by the whole team... about time!
I wouldn't call it an ambiguous ending. ----- SPOILER ----- SPOILER ----- SPOILER ----- SPOILER ----- Our two main characters (three, if you count the dog) make it out alive and are rescued. The last facial expression we see is a smile of relief, pride and love.
Tons of gore, no clue why anyone voted no. People getting eaten, limbs ripped off, bones breaking, tons of blood... very violent depictions of animal attacks.
