Guardians of the Galaxy: Vol. 2 is one of the biggest Blu-ray releases of the month, and what’s more is the title is available on 4k Ultra HD Blu-ray. But with all the various editions you might have trouble deciding which common edition or exclusive retailer edition to choose from. Best Buy, Target and Walmart all have limited editions that have some sort of incentive to buy them. And what about Blu-ray vs. 4k Blu-ray? If you’ve got a 4k TV, and have or are thinking of getting a 4k Blu-ray player, then the Ultra HD version is a no brainer. Guardians of the Galaxy: Vol. 2 on 4k Blu-ray features High Dynamic Range (HDR) color through Dolby Vision and a soundtrack provided in immersive Dolby Atmos audio. Extras on all the Blu-ray releases include “The Making of Guardians of the Galaxy Vol. 2,” “Visionary Intro,” “Guardians Inferno Music Video,” gag reel, four deleted scenes, and audio commentary. Oh, and by the way, Guardians of the Galaxy: Vol. 2 has already been released to digital formats including Digital UHD, so if you’ve decided to forgo movies on disc check out this review of GOTG V2 early digital release.
