This "sad dad" thing is new news to me. Joel and Kratos are the only 2 that come to mind and that's just 2 games so I don't see a problem.
I think sad dad is the wrong term to use. I think third person, action adventure with strong cinematic focus is a little more accurate. I do think people exaggerate this a bit, but Sony has definitely been focusing on games like this a lot more in recent years and I think that some people were a little afraid that they would continue focusing more and more on games like this and less on other types of games. The ps5 reveal seems to have put that fear to rest for some people because they showed a large variety of games and had little focus on these big cinematic games.
