The Grandmother is the first real short-film from David Lynch. What I liked about it is that the film actually tells a story. I disliked Lost Highway because, to me, the story (or lack thereof) was only an excuse in order to put Patricia Arquette naked in most of the shots.
Here, there is a very clear, simply and at the same time very complex story.
The movie pushes boundaries and we can clearly see that we are in front of a young artist finally being able to push his vision into art. What I loved is that there can be multiple interpretations of the film. The Grandmother is a film that makes you think. It is so rare to have to think in front of movies that it is highly important to mention.
I loved the way the characters are communicating. This was a highly original idea. The father is yelling "Mike" in a very obscure way, the mother is screaming, the grandmother is almost howling.
Meanwhile, this may feel like an obscure experimental short-film, I believe it is actually the opposite. A very fun experience that I recommend.
