*don't waste your time*. Most of the movie happens in a sort of multi-floor prison where the top levels can control the food that goes to the bottom floors. This created a sort of class structure where top-levelers had pleasure on denying food to the bottom levels, although the floors were sorted periodically. The protagonist started to question this structure and tried to change it. Although starting well, the movie lost its track trying to be too much symbolic and enigmatic. The ending was very disappointing leaving too many loose ends that should have been closed.
