Unlike much science fiction, this movie focuses less on effects and action than on the psychology of the main character. It can be seen as slow, but the director wants to make the point that the main character's life is boring and meaningless. It's not the alien vibrations that matter--it's that this experience makes him feel special. The aliens chose HIM--and now his horrible life has meaning. Our search for alien life is a search for meaning. This is more like a low-budget Arrival than Star Wars.
