As a 4K Blu-ray superfan, I recommend these 7 discs in Amazon's sale

The palette of blacks in Matt Reeves' take on Batman – which stars Robert Pattinson in the titular role – deserves to be seen from the best possible source.

Lock yourself in a very dark room and enjoy all the subtlety and nuance in this visual treat – which streaming can't deliver with the same justice.

You needn't be a Batman diehard to enjoy this one. If you've watched The Penguin HBO series then expect similar vibes – you won't be able to keep your eyes off the screen.

Some might know this as Live, Die, Repeat, which perfectly describes the movie. This is one of the more underrated sci-fi 'stuck-in-a-loop' movies I've ever seen –and the 91% Rotten Tomatoes score certainly concurs.

The 4K remaster brings a more contrasty yet detailed picture, with a bombastic Dolby Atmos sound mix that really elevates this movie experience to another level. It's a must-have for any movie collector.

This Bob Dylan biopic stars Timothée Chalamet as the famous singer-songwriter – and it blew audiences' minds, as its 95% Rotten Tomatoes score attests.

As with any music-led production, it's the Dolby Atmos mix that you'll really want to soak up from this flick – in its best quality possible.

Guillermo del Toro's masterpiece split the crowd somewhat, but critics truly loved it – as the 92% Rotten Tomatoes rating tells you. Oh, and the Academy Award for Best Picture.

The film follows a mute woman, Elisa (Sally Hawkins), who works in a high-security secret lab – which happen to house an alien-like being who lives in a water tank. An unusual love story unfolds.

Okay, I know, this isn't one for everyone – I'd thought the same until I experienced a classic scene in a custom-built cinema room a few months back.

That experience showed me that The Greatest Showman is worth it for the soundtrack alone – and, in particular, the way it's so perfectly matched and directed with the on-screen visuals.

It's much loved by audiences, too, with 86% on Rotten Tomatoes proving that point – to the contrary of many critics.

The Martian is a truly exceptional movie – as its audience and critics' scores reflect on Rotten Tomatoes, at 91% apiece.

That score should be even higher for this 4K Blu-ray version, however, as the high dynamic range (HDR) re-grading gives so much extra zing to the colours and brightness – it truly changes how this flick feels.

Often quoted as being the ultimate disc to test the best-of-best audio-visual systems. If you've got one of the best OLED TVs in your possession, plus a superb surround sound system, then this will push it to the limits.

I remember watching this one afternoon in a Dolby Vision-certified cinema in New York City. It's lived with me ever since for its sheer visual impact – and this 4K format is the next best way watch.
