For Christmas I got a new subwoofer, and $100 gift cards to Best Buy, which I bought a new surround sound system (Sony 4K; 7.2 Channel Dolby Atmos). I hooked it up yesterday and watched Vendetta for the first time in 4K, and it was so cool! I liked the clear picture and the realistic sounds. Seriously, I hope they release more of my DVDs and Blu-Ray movies in 4K, because it's so cool.
