*spoiler alert*
I gave up watching half way through because the movie is so illogical. The guy has so many things at his disposal and instead of throwing stones, brick, cans, pipes etc out of the window, he chooses to throw only a piece of cardboard. He bangs at the window with a saucepan every time but when the lady enters the building to investigate, he does not. Why? And burning the grills instead of the door. Come on! Way too many loop holes and not worth a watch.
