I had the DVD before, and upgraded to 4K. Yeah, I maybe should have known better (I am an old man and a military veteran as well), but I wanted to see 4K, HDR, and DTS:X pushed to their limits. They were. As for the movie itself, well, it was often inane, but also often loaded with what any 15-year-old would want. (I may be old, but I still remember when I was 15, and back then I would have loved this movie.) I am also a sucker for alien-invasion movies, at least if our side wins! However, the movie did have two rather blatant flaws that I chose to ignore, but which were still significant. First, there is no way a goofball with an arrest record (earned right near the beginning) could get into the US Navy, and especially into the US Navy as an officer. Sheesh. Second, there is no way an anchor snagging on anything on the shallow area of the ocean bottom could yank around a ship as massive as the Missouri. The chain would have snapped or ripped out of its mounts, or the object snagged would have torn loose, and the ship would have proceeded along in the same direction. Still, it looked cool, and I am glad the goofball turned into a leader.
