The Apple TV 4k has some great features, such as a redesigned interface in 4k HDR and the ability to play 4k HDR movies from the iTunes Store. However, there are also some downsides, such as apps that don't support 4k HDR being upscaled in strange ways, and the lack of support for Dolby Atmos sound. Additionally, the Apple TV is a bit expensive compared to its competitors. The reviewer believes that Apple needs to better understand that their TV box is just one part of a larger home theater setup and should focus on making deals with other companies to improve the overall user experience. Furthermore, the lack of support for 4k and HDR on YouTube is due to Apple's inability to make deals with Google. Overall, the Apple TV 4k has potential but falls short in some areas.
