Insane, exhausting but completely unique and certainly worth a watch for anyone who has even a passing interest in challenging cinema. The effects may seem dated now but they have a tangible, tactile element to them that is both technically impressive and disturbing. Unfortunately, you may get a little lost in the story at times and the pace is fairly relentless. At 67 minutes it's concise and it needs to be, there's a lot going on and you're bound to get pretty tired. Definitely recommended for cinema enthusiasts and those looking for something a little radical, casual film watchers beware.
