The Fire UI layout feels well thought out and intuitive. Amazon hasn't been narcissistic with its recommendations and doesn't just pop up shows and series from Prime Video, but from other apps too. However, in the 'My Stuff' section it's only Prime Video shows that pop up. Netflix and other apps don't show up on this list at all. The Fire Cube's picture performance is decent, but not outstanding. While it manages to do the basics well enough, it appears to lack the effort required to add the subtle touches that can turn an image into a truly captivating and cinematic experience.
Watching Thor: Love And Thunder on Disney Plus in 4K Dolby Vision, there are some positives to the picture, such as sharp and clean skin and environmental textures with well-defined outlines. However, as Gorr enters the paradise oasis, issues with the Fire TV's color handling become apparent. The colors appear lackluster and muted, and the foliage lacks punch and vibrancy, resulting in a flat and unengaging image with mediocre contrast that is not much better than the cheaper Fire TV Stick 4K Max.
While the Fire Cube's picture performance may not be exceptional, there is a noticeable improvement in its motion handling. In the title scene of Glass Onion: A Knives Out Mystery on Netflix, the juddery motion of Lionel walking down the pier as a boat passes, which was observed on the Stick 4K Max, is not visible. Generally, the motion appears very smooth and stable, likely due to the more powerful components of the Cube.
