I think Spielberg does remarkably well at painting a realistic picture of the brutality and despicable nature of WWII and the Holocaust. The film is exceedingly well-cast and is a testament to how masterful the director is at his craft. Certain parts had more exposition than necessary, but it succeeds in creating a world that no one cares to return to, save for film.
I've never been a huge Spielberg fan, but I've always been fascinated by the Holocaust and the Third Reich. I appreciate Spielberg's sentiment at attempting to get the public to know of this tragedy, and the film is all in all quite good. But if I'm being completely frank, this film will never be a great film for me, because there are so many superior Holocaust films. This is just a feel-good film about a tragedy.
