You should get the standard 4k, after some more research, the 4k is a big step up from the standard bluray. Hope you and the family have a fun and safe 4th of July!
I liked enough about Jaws 2 to justify a 4K repurchase to upgrade my DVD copy. In the closing scene with the cable, Brody needed a better buzz line than "Open wide .... say ahh." How about this rewrite: "Here .... come floss the flesh from those pearly whites, you son of a ...."
I like it, great idea! Love that ending battle, Jaws 2 is good enough and a fun time to justify getting it in 4k especially if your a fan of Jaws or other shark movies
