Planet Earth II
Possibly the best visual experience available on 4K HDR, Planet Earth II is a staggering achievement - it travels to the far corners of the planet to uncover the delights of the natural world.
Each episode covers a particular setting (islands, mountains, jungles, deserts, grasslands and cities), and the 4K Blu-ray delivers all this imagery in crisp detail and with a wonderfully vibrant and realistic palette.
In fact, why are you still reading this? Go out and get this disc pronto.

Guardians Of The Galaxy Vol.2
It may not reach the heights of the original Guardians, but this sequel is an enjoyable entry into the Marvel Cinematic Universe.
This 4K disc delivers a bright and colourful picture, with the HDR bringing out the intensity of the vibrant colours.
It makes for a picture that pops and glows more than its Full HD counterpart. The Atmos soundtrack is nicely judged too, loud and busy without missing a beat.

The quality of DC's film output has been variable, but Wonder Woman serves as a relief from the series' grimdark tone.
Gal Gadot is wonderful as Diana Prince, and this 4K disc is just as good. It delivers a bold, colourful and detailed image that brings out the film's period decor and tailoring.
The Atmos track can rumble with the best of them, offering plenty of heft and power.
It's a fine origin story, aided by a great 4K presentation.

Blade Runner: The Final Cut
Ridley Scott's Blade Runner is one of those films that simply must be seen on as big a screen as possible.
The disc is a fantastic representation of the film: sharper and more expressive, with colours that are not just brighter but more intense. The hellish landscape of Los Angeles 2019 looks stunningly good.
The Atmos soundtrack offers depth and dynamism, with Vangelis's synth score setting an ominous and spiritual tone for the film.
If the goal of 4K is to get closer to the director's intent, then this disc is a fabulous achievement.

More after the break
John Wick: Chapter Two
We'd argue that while the original John Wick is a better film, Chapter Two is the more entertaining. It expands the series' mythos in fun ways.
The disc produces a detailed image that's a good test for colours and black depth. The Atmos track is enjoyable, adding appreciable height and proving to be adept with small-scale dynamics.
It's an entertaining 4K HDR effort that once again shows that Keanu Reeves is not a man to be messed with.

The Oscar-nominated comic-book film gets a cracking 4K disc as Hugh Jackman's Wolverine/Logan bows out in style.
It's shot digitally, but Logan has a film-like quality that remains sharp and clear. Despite the serious subject matter, it's a colourful film - scenes have a lovely sense of warmth, texture, and richness.
The Atmos mix has plenty of bass and detail, making for an atmospheric, energetic and at times moody track.

Sony and Marvel teamed up to reboot Spider-Man again, and the results are very entertaining.
Despite reverting back to Peter Parker's teenage years, it's a fresh and engaging take in which the school scenes are better than the action sequences.
A charming and funny film and an appealing take on the character, the energy of this film will really grab your attention.

Close Encounters of the Third Kind
A fantastic piece of sci-fi, which often gets omitted in the discussion of great Spielberg films. This 4K disc should bring it back to prominence.
It's a great transfer from Sony, retaining the film's grainy look, with fantastic detail and an appreciable HDR colour boost. There's no Atmos or DTS:X, but the 5.1 soundtrack is a strong, detailed effort.
If you missed the film during its brief cinema release, or haven't seen Close Encounters Of The Third Kind before, you need to watch this.
War For The Planet of the Apes
This trilogy capper is arguably the best of the bunch, as Andy Serkis' Caesar attempts to lead his apes to salvation while trying to curb his need for revenge against Woody Harrelson's Colonel.
Despite being another upscaled-to-4K effort, there's arguably more detail and a greater range of tones on offer. The soundtrack is a precise and subtle affair that opens up the soundstage - especially in Atmos - in a welcoming way.
War may not be packed with action, but it serves as a great conclusion to the series, and to Caesar's story from young ape to inspirational leader.
Director Edgar Wright returns with another kinetic and idiosyncratic film in the musically-obsessed Baby Driver.
The real draw is the integration of music into the narrative, with the Atmos track an accurate and spacious effort that allows the music to soar. The image is solid, retaining the film's sense of colour and detail.
To some it may be gimmicky, but Baby is a stylistic, flavourful film and an impressive feat of movie magic.

Blue Planet II
If Planet Earth II left you hungry for more wildlife in 4K, then you'll love David Attenborough's stunning deep-sea documentary series.
Blue Planet II is full of vivid coral reefs, bright and colourful fish, wondrous creatures that change colour, alien-like beasts that look creepy and fascinating at the same time – they all look fantastic in sharp, clear and vibrantly realised 4K HDR.
This a must-watch for any TV fan.
