I have not seen this movie yet, nor have I read the novel. In fact, I have not seen any version of this story, including the recent musical. I have this 1997 DVD though, as well as the London cast recording, both of which were gifts. That having been said, I just want to point out an error in two of the reviews...
I am no fan of Hollywood, usually preferring foreign versions of most movies. Unfortunately, reviewers dad-hunter (j. hunter) from the UK and harrsman5 from Chicago have it wrong. Dad-hunter wrote, "For reasons known only to Hollywood" and ends his review with, "Badly done, Hollywood!" Harrsman5 asked, "I wondered how badly Hollywood could screw this up," and said that the movie makers "Hollywoodized" the story.
This was a British production, not a Hollywood project. This is clear from the credits, as well as the IMDb.com description. It is a co-production for the BBC by Carlton International Media, Ltd and WGBH. Carlton and the BBC are in the UK, and WGBH, a PBS affiliate, can hardly be considered Hollywood. While harrsman5 may be confused by seeing it on Masterpiece Theater here in the US, I was very surprised by dad-hunter's comments since s/he is from the UK.
As for critics who chastise it for not being faithful to the novel, I think it's better to rate the movie on its own merits. Many of us have never read the novel, nor plan to. When I finally view it, I will judge it based on the movie alone..
