The plot summary on IMDb doesn't do this film justice. It's a slow-burn drama about the family of a retired Guatemalan general on trial for war crimes. His daughter, an intelligent and compassionate medical doctor, is finally reckoning with what her father participated in, and her moral struggle expands to the rest of the family. At the same time, the general's sins are coming home to roost in a very literal way.
There is an element of horror here, but I was much more enthralled by the family drama of the piece. Unfortunately, it does copy one thing from other thought-provoking horror films and fails to fully stick the landing. Still a wonderful film and one that I'll think about for a long time to come. Brilliant cinematography and sound design, see it in a well-equipped theatre if you can.
