The use of colouring was effective, we thought that the choice to put the film in black and white made it creepier. It was obvious who the protagonist was and who the antagonist was comparison with one another. The hand held shot made the fil very chaotic and the random shot of the train was effective. From the high angel shots of the girl you can tell that she is in peril which conforms with conventions of a thriller. The use of diagetic sound was effective. We really enjoyed the idea of the film and there were obvious clues that the protagonist was going insane.
On the other hand we liked the shots but they could improve by being put together properly so as they look fluent and follow one another properly. The film would also be improved by some music which would add more tension to the film although we are sure this will be added soon.
