Bloodborne is one of the best action role-playing games ever created. In terms of polish, combat, music, and atmosphere, it is one of FromSoftware's top three games of all time.
Bloodborne is a Lovecraftian horror and action game and is the best in this category. Dark Souls brought FromSoftware to the West's attention, but Bloodborne solidified it. Upon release, it brought wide critical and commercial success to the company, winning several game-of-the-year awards.
The faster and more aggressive combat of Bloodborne and its improved graphics brought FromSoftware to a much wider audience than what Dark Souls has achieved. It is one of the best games of all time.
