I watched it again.

What I like:
-The setting
-The "music" at the end of the trailer which brings some tension

What can be improved:
-The far to long scenes in the starting scene where the person is running away from something. Camera should change position every 1-3 seconds to make it more thrilling.
-The end! Who's that guy and why is he just smiling? It did not make me want to see how it is going on because there is nothing misterious or special. A voice can tell some parts of the story while these 2 scenes are shown.
