Oh well, a missed opportunity to upgrade a classic. I have the opposite view. The reason I buy blu-ray titles is to experience a high quality viewing experience. If I already own the title on DVD and the blu-ray improvement is minimal and no additional extras why bother (in this case less). As one review noted, this is a 3 hour plus movie on one 50 gB disc with 8 gB dedicated to the SD extras. How could it possibly look good!
05/05/13 - Wow, this title is already discounted to $9.99 and it hasn't been released. Guess I'll take a chance at that price......
As per the blu-ray.com review, there was some restoration work done -- but not on original elements. Take a fifth-generation recording and "clean it up" and one has a cleaned-up version of a fifth-generation recording.
As "M. Gibb" notes, the dvdbeaver review is kinder -- and not inaccurate.
If the quality of the restoration is good, the Blu-Ray will take care of itself. We saw a supposed "restoration" of this on the big screen last year in the Cinemark Summer Classic Movie Series (2012). Zhivago was unbelievable. The Great Escape was technically a huge disappointment. My DVD looked better at home. I don't know why they don't just do a "real" restoration. But I'm not going to re-invest in a Blu-Ray version until there is a real restoration. I've already owned this movie in 3 previous incarnations. So I don't need it until I can get a real restoration.
