"It seems to me this is a european/author movie so I don?t know if the rule state the goal and stakes? should be respected."
The conventions of story telling apply regardless of nationality and geography these are universal and true to all humans. In short the answer is a resounding yes, state the goal and have stakes.
P.S
This is not a rule rather a convention that has been found to work more often than the alternatives. If the writer aims to sell the story and engage a large portion of the viewing audience then it would be best advised to comply with these conventions.
Hope this helps.
