The opening scene does promise a very good movie. But movies can be illusive.
The story line is thin, but ok enough, there are more movies which are good enough with a thin story.
The lack of continuity is a problem in this movie. Also some sequences are cut very strangely, if there are a sort of pauzes in a supposed fast shooting scene. Most prominent in the sequence (1:15:45) when they are in a small room, with the girl on the bed, what then happens lags flow totally. Also in that same sequence the foley sounds are mainly terrible absent. Then the sound track is mainly absent or present but with the wrong music.
Finally, the movie suffers also from the directing skills.
Still it can be an interesting movie to watch for film academy students to figure out about what exactly is wrong with this movie.
