"All of the Sonic Boost Era games are janky", said no one ever. That really only applies to
Unleashed,
Forces, and the HD versions of
Colors.
Sonic Generations didn't have any jank. Some minor problems with level design, but no jank. Gameranx is another mixed opinion, yet he like it overall. I like the guy, but this a case of me judging for myself.
I actually watch gameranx exactly for that reason; honest flaws. It's the same reason why I watch ACG, SkillUp, Angry Joe, and Maximillian Dood. They always try to give honest opinions, at the risk of flawed arguments and mistakes. But that makes it all the more natural, and I get to hear on their thoughts on why they think the game is genuinely bad, good, or in the middle.
And then there are places like IGN, where the reviews are paid or seriously biased, and usually like to double down on their stance making their reviews intentionally headstrong and flawed. I.E. Alien Isolation review, Evolve Review, Fortnite review, etc.
There are also people who make ironic and sarcastic reviews, but I just feel they are doing it for clickbait.
At the end of the day, I guess I appreciate reviews that are geniune. Someone can criticize Witcher 3, one of my all time favorites, to be a bad game for really good reasons, I'd happily accept their thoughts and would love to talk more about them. I just don't like reviews that makes the reviewer sound like an asshole
