The ending (spoilers)
Very good movie but it's sad how the movie ended :(
It's good to see a different ending rather than the cliché route but I wanted Verónica to live. Unlike most of the main characters, she was very likeable and smart (well except calling for the dead obviously)
Sad that nobody believed her except her siblings. Well, if we get a sequel. I hope Verónica/devil will haunt those supposed friends of her.
