I only think it's annoying because Sony was banging thier drum really hard about believing in generations, amd then kind of ended up being mostly full of shit about it.
In reality, I think they've done a pretty good job. While getting games designed specifically for PS5 is pretty amazing, the reality is that Demon's Souls, Returnal, Ratchet, Miles, Horizon FW, Gran Turismo 7, and God of War all really do still look incredible.
Also, visuals, or perhaps more specifically, the ability to render a game in a way that only next-gen machines are capable of, isn't necessarily the most important aspect of a game. Most of favorite games this year are cross-gen, and I feel absolutely spoiled for it. Psychonauts 2, the Artful Escape, Death's Door, Quake Remastered, have captivated me just as much as Returnal and Flight Sim.
