I watched the short of this movie a while back and then discovered they had made it into a full length movie!
***Spoilers***
Firstly if you were ever bullied growing up because of your weight, this movie may be triggering for you. The writer pulled no punches and the remarks are really upsetting and I felt so bad for Sara, I think, unless you've experienced bullying to some extent you'll probably think it's average, however you need to put yourself in her shoes.
She gets no sympathy from her family, her mother is very strict and has no empathy for Sara at all, her father is slightly better but fails to stand up for his daughter. Even her younger brother makes fun of her. The whole town pretty much calls her fat and make jokes at her expense, so, when the killer stands up for her in a twisted kind of way, you can kind of see why there's an attraction there on Sara's part.
The 2nd act does go on a bit too long but it shows the struggle Sara has, wanting to tell the truth, but also afraid to, because the killer is the only one who has stood up for her.
She does do the right thing in the end, which is a nice little twist, as I thought she had killed her bullies.
Laura Galán is amazing as Sara and all rhe actors were fantastic! I watched the original version in Spanish, and by all accounts, its better than the dubbed one. But I always try to watch movies in their original language anyway.
All in all, I'd give it 5 out of 5, good direction, great writing and fantastic performances.
