Twin Peaks
In these weird, obscure movies' boards, it's an unofficial rule we must have a David Lynch similarity thread, so I may as well start it. This movie resembles Twin Peaks a lot, especially the final episodes, when Agent Cooper is trapped inside the Black Lodge. We have a protagonist inside a space, being held there by evil spirits, unable to leave in spite of many attempts, and where logic breaks down.
This world is a comedy to those that think, a tragedy to those that feel.
