It's stupid but understandable, to be honest. I'm pretty sure this guy knew his review would ignite some sort of reaction, in the hope that it would get a lot of clicks to his site. And sure, you can say that not everybody likes open world games, or thinks that the zelda games are for 6-year-olds. But a professional reviewer should be able to rate a game objectively and place himself in the shoes of people who do actually care about the genre. Personally, I never played any Zelda game as it's just not my thing, but from seeing gameplay clips of BOTW, I can at least understand what the fuzz is all about.
