Games like Last Guardian are pushing the medium as an art form yet "gamers" are grumpy and mad

Yes it's such a form of art that each frame stays longer on the screen than necesary. Besides isn't every game some sort of art since its made by artists. This might be a more abstract and more direct form of art, something which we like to call artistic. But every game is a form of art in one way or another.
