Query: A movie that creeps up on you

This is one of those movies that creeps up on you. It starts slowly, but it builds up very well, and I found it only too believable, very affecting, and quite amazingly gripping. Great performances, and certainly it bears some comparison to The Godfather, though it's not quite as richly-textured as that masterpiece. Still and all, a most enjoyable movie.
