Can't say I share the negative view. While I haven't played too many things that blow me away, I've been plenty happy and had plenty of good games to play.
While Witcher 3 took a while to get there, the game looks and performs fantastic on PS4. As good as PC? No, but that's the console breaks.
Batman on the other hand while disappointing and kind of bad was one of the best looking and best presented game I've seen in a long while. Battlefront as well is so damn good looking.
Bloodborne may not be a revelation, but to me it's the first Souls game to click for me and the combat is always engaging.
I've enjoyed aspects of MGSV and its polish is well above anything last gen. While I don't think that can be said about Rise of the Tomb Raider it's at least been a damn good action adventure game. I've also been replaying Advanced Warfare which does honestly look great to me and is filled with many a great cod cinematic scenes. It's one of the best CoD campaigns in a long while.
I don't think there's been anything amazing or world breaking, but plenty of solid good games. Halo 5, Sunset Overdrive, Dragon Quest Heroes, Until Dawn, Ryse, Dying Light, battlefield 4, and Destiny are all new games that I've enjoyed. They don't feel "next gen" besides visual polish(well maybe Dying Light) but that doesn't mean I can't enjoy them. Yet I see how some can feel fatigued towards games as a whole.
Outside of Witcher 3 I haven't played a game that's enormed me with its story, art, characters, music, and gameplay. Then again maybe that's hard to do sense I'm an adult now.
Yet I feel next year is filled with amazing looking things. Final Fantasy, Persona, Ni Oh, Nier, DQXI, Mirrors Edge, Stat Ocean, Quantum Break, Zero Dawn, Uncharted 4, and so on. So there's potential for many memorable games.
