Cop-Out
The film is a near-masterpiece but the punch pulled at the last minute lessens the impact.
*spoilers*
The captain is hardly a character in the film so his interceding to get Mikkel's wedding ring back and then being executed smacks of a dramatic cop out. It was as if they realized they needed SOME darkness at the end, but did not have the spine to kill the protagonist so, instead, they elected to kill off a minor character who, really, was on screen for probably six minutes, total.
