That's too easy on Spielberg. He can and has made serious, meaningful films, such as Saving Private Ryan. He chose however with Munich to take a serious subject and use it to push a liberal, appeasement POV, and in so doing has betrayed his blood.
I didn't like Private Ryan too much. It got boring, quit watching after 40 minutes. I'll admit the 20 minutes of the D-Day landing and invasion was very well done
