There are a number of excellent movies that get undeserved average ratings because the number of voters are small and a few people who lack sensitivity just don't get it and give a superb movie like this an abysmal rating.
First of all, having read the book by Isaac Bashevis Singer, this movie has succeeded, in my opinion, in capturing the essence of the book. This is a rare achievement, most movies fail to do justice to the books they are based on. This is not to say that the film has not had to make changes to the story, but that this movie has successfully translated the story into the cinematic realm.
The movie has at least one scene that is even more powerful than the way it is depicted in the book. I don't think I'll ever forget the emotional impact this scene made on me (I don't want to spoil it for anyone who has not yet seen this movie).
Second, this is such a great movie that it stands on its own. You need not have read the book beforehand. I saw the movie before I read the book and I firmly believe both are masterful. It is one of the finest movies I have been lucky enough to have seen in a movie theater (I just hope that the DVD version has not been cut too much).
Finally as some other reviewers have pointed out, Alan Arkin and all of the entire cast have done a superb job in bringing their roles to life. The directing, costumes, music, are all realized with masterful skill and elegance.
Forget about the philistine reviews and see this hard to find movie -chances are you will not be sorry.
