Like wine tasting

The recent game between Carlsen and Mamedyarov from the Grand Chess Tour event has left me a little conflicted. I cannot decide whether it is some high level brilliance well above my level of understanding, or a club hack played by two GM's. I am leaning towards the latter, and wonder what someone unaware of the identity of the players would make of the game. It might be worth conducting such an experiment in the future, if such games become a feature of top level chess.
Here it is in all its glory. Comment are welcome.
