Angry Joe is actually one of the better game reviewers I have seen. He admits his bias and tries to explain his rationale thoroughly to allow viewers to understand what exactly works and is broken in those games. I think he has some poor tastes, but that is because he came from console gaming and not because of any dislike for complex ones.
Regardless of my taste for games he seems to like the most and for things that make games great for him as well as those that put him off games, I think objectively one has to admit he puts lots of effort into his reviews. He really does play through the games he reviews.
Also, there's some obvious honesty going on and i respect that. One more thing that i like about his work is that he's neither malicious nor too benevolent a priori, when he approaches any game.
The thing that I subjectively don't like and that isn't satisfying for me is that he's obviously quite a bit of a nextgenfag and consolefag. He also focuses on new AAA titles, which generally don't interest me.
But all in all, I'm not ashamed to say I like his stuff. Yes, he's not "hardcore", he's not "oldschool", he's not even very knowledgeable when it comes to classic games, but what he does - he does well.
