Until today I had not heard of this short eight minute something movie but came across it whilst reading an article about world renowned Mexican film maker Guillermo del Toro. It is easy to find on a free well known streaming website that begins with the letter "Y". I don't speak Spanish, apart from a few words, but thankfully it has English subtitles. Geometria translates into English as "geometry" and this short story is of a teenage student that is struggling with his school geometry so he summons a demon! This does not bode well for his mother! I am not giving it away but as well as being well made and quite funny it comes with a neat twist at the end.
