Do games really need to look better than Uncharted 4?

[Qwark]

Just check a random animation movie and you will conclude it can become way better. If you bought Ratchet and Clank compare the cutscenes with the gameplay, the latter look way better. Even tough Ratchet and Clank looks extremely gorgeous for a game. To me it even is the best looking PS4 game, but I would lie if I said that I don't want to see the next installment to look better wit the same fluid gameplay that is. Same goes for Naughty dog games.
