To understand why this movie got from me only 4 you must understand that the content is only 20 minutes, but is stretched to more than an hour with boring stuff. For the first 15 minutes nothing happens. The story starts with a bum that thinks himself to be a great artist and his sad mother who has to support him and tries to bring him to reality. Then you have about 10-15 min of him trying to sell his garbage as art. Then the real story starts as he discovers a strange hole in the wall of the room he rents. Unfortunately too little is spent explaining stuff about the hole and too much on his artist life. With the help of the voice from the wall he manages to sell his crappy mobiles and that is about it . In the end he leaves the hole and puts a painting frame on top of it that does not cover it trying to be artsy and failing. Although the movie has great potential in the story of the voice in the wall the author chooses to be a failing artist and a bum instead and concentrate on how hart it is to be a struggling artist (read bum). The main character (and most except the mother and his uncle) are not the kind of characters you would care about so nothing that happens to them seems important. The hole does not become too big and is never explained anything about it. Here is my theory on the hole and how it should have developed: the creature from the hole is lovecraftian monster that tries to get in our world. It needs human energy to cross the tunnel and enter and being a big creature it needs a lot. Its attachment to Herman is because he called it and is the main anchor to this reality. His art incorporates parts of the creature itself which the creature can use remotely to absorb energy from the buyers. If the creature would manage to get close enough to this world it would start consuming humans as apparently this is what eats. But of course the author chooses to play the bum part...
