I don’t think there was moral ambiguity in “Munich”. It was pretty clear who the terrorists were. That said, it did show that killing people, even terrorists, isn’t totally clean. I guess there are plenty of action flicks where it’s black and white, though.
Pretty clear what Spielberg was going for.
He wanted to play both sides.
That's why I won't watch Munich again.
That lukewarm attitude for me makes it a "see once and forget" type of film.
