My son bought me a copy of The Incredible Hulk (2008 with Edward Norton, Liv Tyler, Tim Roth and William Hurt), in 4K UHD. Wow. They did a ggreat job upconverting this movie. It looks absolutely new. The sound was great (DTS:X), picture quality was very good.
My only gripe was that a few times throughout the movie, the dialogue was quite low compared to the rest of the sound mix. Also, because it is from 2008, the tech used in the movie is quite dated, but that's to be expected. Overall, I really enjoyed watching it again as I hadn't seen it in quite some time.
