The 4k set is a two-disc set containing a UHD disc and a regular Blu-Ray disc. The 4k disc has the theatrical version of the movie and all of the extras. The regular Blu-Ray includes the director's cut of the movie. It looks and sounds great in the UHD format. The movie stays faithful to Kubrick's version of The Shining, which Stephen King really disliked, but also incorporates the ending of the book version of The Shining (having Danny take over Jack's role at the end of the book) while fighting Rose Hat. There is about 45 minutes worth of behind-the-scenes and making-of material included as extras. It's not a ton of bonus content, but what was included was good. Overall, the movie is excellent. It is very violent, and there is some nudity, so it earns the R-rating. Ferguson dominates nearly every scene she is in, and McGregor does a great job playing the adult version of Danny. Kyliegh Curran does a wonderful job as the child lead in this movie, and if there are more stories to be told of her character, she would do a great job. It is definitely worth checking out.
