A nice idea. A not great result. Few young people as part of an experiment. A ball destroying a painting. A locked space and the sounds from it. The fear and the result of opened door. Nothing special, at the first sigh, because you remember other films about young people as parts of medical experiments and the feeling about it is only to see a sort of sketch. Few good intentions, drawings of performances, good atmosphere and not bad cinematogtaphy and a huge potential. And nothing more, against the desire to give more.
