First things first, this isn't really horror per se, but I suppose going insane would be considered horror. This film focuses on senses in every way possible, sight, sound, taste, smell, and touch. It's those senses that intensifies over time and for some, becomes a crutch into self isolation as it turns into psychological paranoia.

The film introduces you into each of these senses with spiraling inner thoughts spoken out as the film goes on, and then leads to full blown insanity that ends in surrender. If you focus on the underlying context without feeling bored, you'll understand why this film plays out this way.

Complete insanity in doses.
