As a great fan of (most of) the Metal Gear games, I'm very skeptical about Death Stranding. I do have the idea that Kojima has no idea what his game is gonna be about.
That said, I'm completely fine with that. You sound like Kojima owes you (and the public at large) some kind of explanation or justification for his 'art'.
It is kinda silly to see everyone so hyped about pretty much nothing. But hey, that's not my problem.
No one wants or demands that he owes us anything, the problem is he gets a free pass because of his name if it was any other developer people would have started asking questions.
People do tend to cut him some more slack than others, I agree. But in my opinion he's earned it.
