Back when it was released during the late 1940s, this film was really quite something. It was a serious drma which tackled the issue of prejudice, specifically anti-semitism, something that really struck a chord given the historical evetns of the years preceeding it's release. I can see why it won some Oscars (including Best Picture), but I can't really say if it was the most deserving of the award or not.
It is a good movie though, although it comes across as rather tame and typical by moden standards. So, in order to really enjoy it, you just have to force yourself into the same environment that the film was made and takes place in. You can get enjoyment out of it if you don't do that, but you might not find the film to be as impactful, either.
It is a tad bit boring, and I think they could have handled the issues a little better, but, given the circumstances, they really pushed the envelope for the time, and did the best they could. I do like the performances though, because Peck is as reliable and watchable as always. The others are good too, but unfortunately, the score makes everyone seem more melodramatic than was probably intended.
All in all, a decent enough film that tries to explore some serious issues. Some of its relevancy has worn off, but the principles remain. If you want to see how important social and cultural issues were dealt with via film in the past, you could do a whole lot worse than this.
