The company who performed the digital transfer did a horrendous job. They left in visible dust specs and the sound volume kept fluctuating. In regards to the release of the Blu-Ray disc, it comes up short with bonus material. The DVD version came with tons of extras and an extended version of the film. The DVD version included the original theatrical release and an extended version.
If you already own the DVD version, I would recommend that you not bother upgrading to the Blu-Ray version until the studio does a better job remastering it and included the extras that were included with the DVD version.
