So you've upgraded to the latest technology and have a 4K UHD system... but what discs should you buy? Let our reviews help you choose with our latest 4K reviews: Ex Machina - Alex Garland's directorial debut is thought-provoking and exciting, with excellent performances from the principal cast; Dawn Of The Planet Of The Apes - one of the few Hollywood sequels that is superior to the movie that came before it, this movie succeeds by providing us characters (both ape and human alike) who are well-rounded and interesting to watch; and Dredd (2012) - exciting and impressively lensed, Dredd is a great update to the material and a strong, modern action film.
