The 4K set is a two-disc set containing a UHD disc and a regular Blu-Ray disc. The movie looks and sounds great in the UHD format, especially if you have a large screen. The UHD disc just has the movie itself, and all of the bonus content is on the regular Blu-ray. There are about 22 minutes worth of behind-the-scenes and making-of features, a short gag reel, and a few deleted scenes. The bonus features probably amount to between 30 and 40 minutes in total. Ultimately, the movie is one of more than 20 in the overall MCU story arc. It is written so you do not have to have seen the others to follow most of it, but it will definitely help if you are up to date with the overall story arc that has played out throughout the other movies. The entire cast, from the stars to the supporting characters, are all great in their roles. Evangeline Lilly does a great job as the Wasp and really seemed to be having fun with her more expanded role. As long as you do not have superhero movie fatigue, this is definitely worth checking out.
