You are hung up on the wrong thing. Parent writes: "[clear consensus that] there was absolutely nothing unusual about it", I quote one of the greats saying the game is "more than impressive", which, at least we should agree, is the exact opposite of claiming there is "nothing unusual about this game". Onus is on parent to come up with a list of grandmasters claiming the game was "usual", at least I provided one refutation but there are many.
