The 4K set is a two-disc set with a UHD disc and a regular Blu-Ray disc. The A/V quality of the UHD disc is great, as the movie looks and sounds wonderful in the ultra-high-definition format. Some of the visuals (especially when they are in the mountains) really pop in UHD. As was the case for the other movies, the UHD disc just has two versions of the movie (the theatrical and the unrated version). The unrated version does not add much to the storyline; it just adds a few minutes to the movie. The rest of the behind-the-scenes featurettes, deleted scenes, and music videos that make up the bonus material (about an hour's worth altogether) are on the regular blu-ray disc. Ultimately, if you liked or loved the other movies, you will probably feel the same about this one. If you hated the other ones, then this is not going to do anything for you. Certainly, many of the same issues that plagued the first two movies persist in this one, chief among them the lack of chemistry between Dornan and Johnson. And, of course, the movie still has a ton of sexual content and nudity, so it's not family-friendly or for the easily offended. If you come in with realistic expectations for it, that it is a decent but certainly not the greatest romance movie, with some drama and suspense, it is enjoyable.
