It seems Amazon is combining the reviews for different versions, so to be clear mine is for the 4K version of the trilogy set.Men in Black is the franchise that, along with movies like Independence Day, vaulted Will Smith into the status of summer blockbuster movie star. The original trilogy spanned a period of about 15 years, from the 1997 release of the original movie, the 2002 release of Part II, and the 2012 release of Part III. As most are aware, the premise of all the movies is that aliens are living free among humans on Earth, and a shadowy, secret, organization called Men in Black keep track of all the aliens, keeping them safe, and in line, and making sure humans are blissfully unaware of their existence. It starred, primarily, Will Smith and Tommy Lee Jones as Agents J and K respectively, who in all the movies have to stop some kind of plot that will destroy Earth, or cause some kind of intergalactic war.All of the movies blended a lot of humor, action, and even a bit of drama, and managed to tell unique stories without being carbon copies of each other, which would be very easy to do in a franchise such as this. Smith and Jones, and later Smith and Josh Brolin (who played a young Agent K in Part III) had great chemistry with each other. And, it seemed genuine from the behind-the-scenes material. If their relationships did not work, it would have never become a franchise that moved beyond the original movie. Smith as a brash younger agent played extremely well off of Jone's deadpan curmudgeonly delivery. And in Part III Brolin did a wonderful job playing a version of Agent K that was different from how Jones played him but was able to include elements of what Jones did with the older version.For those who get the 4K set, the movies look and sound wonderful on the upgraded format. Obviously, Part III looks the best, but even the original is a great upgrade over the original DVD release. Each movie has two discs, one UHD disc with just the movie, and one original blu-ray with the movie and extras. Each movie has at least one general behind the scenes feature, and then several specific featurettes such as, for example, scene breakdowns, how they came up with and made the alien creatures, the special effects, etc. There are also gag reels, trailers, and music videos. Then there is a commentary track on each movie. A lot of material for those who like going through the extras. The only negative to the set is that the discs are stacked on top of each other in their case (each movie has its own case within the outer box). It is a minor point, but it would have been better packaged so that each disc sat on either side of the case in its own housing. That said, I definitely recommend picking this set up.
