Why I can't enjoy this movie.

At the beginning they make it very clear that the fights will be very loud, so I move the volume down.

From then on all they do is whisper. It is like they are trying to lure me to bring the volume up so they can just scream on my face on the next fight.

Very annoying thing. Does everybody in Germany whispers instead talking? why everybody in this movie does this?

Most of the time the background music comes on top of all the whispering.
