Personally I LOVE the "Dad of War" angle.
I like the new camera, change of scenery, and what we've seen of the gameplay, sure, but it's the bigger changes that actually excite me. Kratos being more human? Teaching a son? Growing out a sick beard? Count me in!
Beyond the gameplay and story, in a purely "styyyyyyyyyyyyle" sense, the fact that the aim is for the entire game to be shown in one continuous shot, with no cutscenes, loading screens or cutting between camera angles or cutting forward in time, is NUTS.
Finally, the only thing I was worried about (a lack of bombastic set pieces) has been settled in Corey Barlog interviews where he's said they will still have that in the game (where it makes sense, of course). They just wanted to show an intimate scene for the first reveal to demonstrate the new direction for the franchise.
