Reviews are subjective and I respect their opinions. However... when your review is heavily comedy-based, there can another issue. Case in point: every single time Yahzee reviews anything by Nintendo.
There are some valid criticisms in there. However, he spends about 2 minutes (of a 5 minute video, I remind you) making the SAME JOKES. "Ooooh, here's a comment on how I hate motion controls" and "Ooooh, everyone who likes Mario is just a nostalgia-blinded MORON" and "Oooooh, ANOTHER mention on how I don't like motion controls" and "Oooooh, bad graphics" and "Ooooooh, Nintendo milks their franchises and THEY ARE THE ONLY ONES WHO DO" and "Oooooh, here's a joke about the minimal plot".
And then "Oh wait, I have to actually review this game now, don't I? Not just make the same jokes I make in every single Wii game review? Well, there's only about 2 minutes left, and I need half a minute for the credits, so here are some footnotes on things I did and didn't like. But I also need to spend 30 seconds nitpicking for comedic effect, so that's only about 60 seconds of actual criticism."
The reviews themselves are good. But with anything based in comedy, repetition is one of the worst sins you can commit. And I find it humorously ironic that Yahtzee keeps accusing Nintendo of rehashing by rehashing all his jokes about them.
