I normally don't fall out of favor with critics. Even Yahtzee, who I've sworn off a few times keeps reeling me back in with his humor and opinion.
Moviebob is someone who I actually disagree with constantly; particularly on comic book movies. I thought "The Avengers" was merely okay, and that it did absolutely nothing to elevate the genre or take any risks apart from having a bigger cast of heroes. I also loved "The Dark Knight Rises", liked both "The Amazing Spider-man" and "Man of Steel", and I didn't even hate "Green Lantern" that much. Despite all that, I do watch him because I find he's incredibly good at formulating an argument, and I find he has a bit more class then Yahtzee does.
Hell, even Anita Sarkeesian, who's videos I watched all of successively during the kickstarter debacle has started to bother me. Now, before the legions come to assume I'm bothered because she's the worst thing ever, or that I'm part of that legion by hating on her; hear me out. I get why she blocked comments. I don't like it, but I don't remotely blame her. I also can't imagine what it's like to have several hundred people daily trashing you, and what you stand for, so I sympathize in that respect. Thing is though, she is a critic, and as a critic her opinions are open to be disagreed with. I don't like how her supporters seem to be propping her up as a prophet and that what she speaks must be absolute truth. It's not even that I disagree wholeheartedly with her points [except that Bioshock Infinite is awesome, and I'll happily debate those who disagree], but the absolute way she says it, and the implication that those who disagree are wrong, or worst, immoral for disagreeing bothers me. Her videos are meant to create discussion, and I don't like how there's no discussion going on, and just passionate love or hate knee-jerk reactions.
Oh, there is X-Play I guess. I still watch Adam Sessler time to time, but I distinctly remember falling out with X-Play when the reviewed Metroid Prime 3: Corruption. That may be my own immaturity, they did say it was a satisfying conclusion to the trilogy, but I remember it rubbing me the wrong way when they complained about the extra bounty hunters in the beginning of the game, and that in the future Samus should go without them. That made me question whether or not they even played the rest of the game, where you're forced to tragically kill them off one by one due to their phazon corruption.
