The set is great, but the 4k disc are defectives, all three of them. This is my third set. I've preorder the one with the skateboard, the regular set from another distributor and then this one from Amazon, all defectives! The second movie have 3 chapters in the middle that won't work. I'm really disappointed about this set, because when it play's it's really great. I don't understand how come this set has the biggest problem off all the 4k discs manufacture to date, coming from Universal with the production overseen by Steven Speilberg, and they don't acknowledged their problem and fix it. Universal should have a defectives discs replacement program, where you send your defective 4k disc only(not the complete set) in a bubble mailer with your return address... This shoud be done with all DVD'S & Blu Ray's, don't let this down on Amazon all the time, give them a chance.
