Rated 3/10. Granted the actors did a fair job, but it couldn't overcome how boring and slow-moving this story was.
If you like long scenes with lots of dialogue, then you'll like this movie.
The ending was extremely anti-climatic. So what, it was 50 years ago! Tragic, yes; deceptive, no.
The DVD box write-ups highly inflate the quality of this movie. Gripping? I don't think so.
Looking at the other comments, opinions vary quite a bit. I think it's a low blow to criticise someone else's comments (and naming the writer!) after-the-fact, saying that they "slept through the best parts". How someone likes a movie can be very subjective. Each to their own, right?
