In the run up to release, director Cory Barlog repeatedly stated just how difficult it was to create God of War's "one shot" presentation - with the game not cutting a single time (apart from if you die) from the opening credits to the closing ones - with multiple studios turning him down until Sony allowed him to try it for this revival.
Fortunately, it seems as though his perseverance has paid off, as the innovative camera system allegedly elevates just about every aspect of the upcoming game. In Polygon's 10/10 review, the writer explains:
As a technical achievement, the single shot is mind-bending, a never-ending “how did they pull this off?” Open-world sequences seamlessly transition into cinematic showdowns into lengthy trips in the canoe — without a stutter.
IGN also commented on how effective the camera is:
That intimacy makes those emotions all the more real and impactful. It’s made Kratos relatable enough that I’ve been caught audibly referring to Atreus as “my son” several times since the opening hours.
It sounds as though the new camera not only increases the sense of scale in the world then, making combat even more spectacular, but actually makes the player's journey far more intimate, personal, and powerful.
