I liked this movie for several reasons: 1. It differs from other similarly-themed movies by focusing on the one "war child" (Eero) and his relationship with the two mothers in his life. That was fresh for me.
2. Great cinematography! Many beautiful shots of the Swedish countryside and other nicely-framed shots. One that impressed me was the shot of Eero sitting inside the concrete bunker with the sea and sky in the window next to his head. This movie is worth it just for the camera work.
3. Great acting by all of the actors.
4. Excellent story/plot that kept moving at a good pace.
The one negative comment I would make is regarding Eero's young female peer. She tries to be his friend, but he ignores her and their friendship is never developed, so I wondered what was the use of her character, since she had such a minor role. Maybe it ended up on the cutting room floor?
