Lol, that guy reminds me of somebody I talked to not long ago on YouTube. He kept calling DMC4 Dante 'Donte', as though he doesn't even know where the name 'Donte' originated from (DmC). Kept calling Nero emo without really explaining why, said DMC4 was *based on or heavily inspired by Twilight* for some reason... just weird. I think he had a profile picture of Vagrant Story.
But no, 77 is not mixed, I would categorize it as ''very good''. Mixed is when many reviewers score the game differently, like when one reviewer scores it a 5 or 6/10 while another might give it an 8/10. I'm not sure I've ever seen mixed being used as an indicator of a singular score.
And if everyone who dislikes DmC is a terrorist, I guess we live in a society mostly populated by terrorists, lol.
In my mind, it goes something like this:
50/100 is bad, anything above that is mediocre.
60/100 is decent.
70/100 is good.
80/100 is great.
90/100 is excellent/outstanding, whatever.
100/100 is... amazing? Kind of hard to define this one in one word, especially when everyone has a different mental image that goes with certain words.
