D summed up my feelings. Most reviewers that do the angry/irritated/swearing hyperbole thing present everything as if it's fact without much to back it up, and as a result come across as giant flaming assholes.

Yahtzee, on the other hand, always quite explicitely presents things as opinions and says that if you like certain things, you might like the game. His gags are usually pretty clever too. I mean, anytime I've watched other game reviewers that have a similar angle I thought they were pretty retarded, but even when Yahtzee does a game I genuinely like I find myself entertained.
