Four kisses.

An elderly man is beat up (not shown explicitly). A woman is shot and killed (a little blood on the snowy ground is shown).

None.

Minor drinking. Near the end, there is a ceremonial toast.

Since this is a war propaganda movie, the movie is quite profuse in its emotional side. The scenes are meant to rouse resentment and can be quite sorrowful. This, however, should not be deemed "intense", even for little children.
