5-stars for the print quality. I'm not sure what restoration might have gone into it. I didn't look for any info on that, but it's an old enough movie that such a clean video image as this probably got some love along the way. Maybe it's not at Criterion Collection level, but it's not far from it.
Art & packaging are fine / no complaints.
Haven't looked at any extras in the one disk that comes in this.
Storywise, you can check it out on Rotten Tomatoes, YouTube, etc., but we found it to be quietly enjoyable as a pre-gore horror movie with just enough depth to hold interest. It adds an interesting and sufficiently different "monster" to the classic horror movie monster pantheon. Overall, the writing and acting were fairly Hollywood. The one inspired part was the origin story of the mummy, which is tragic & horrific, even if the person doomed to the mummy's fate is not an especially sympathetic character.
My biggest kick from this movie came from seeing Peter Cushing (Star Wars' Grand Moff Tarkin) much younger, and cast as the good guy, and Christopher Lee (Star Wars' Count Dooku) ~50 years younger, as the Mummy. Lee's longevity as an actor is impressive.
