I generally only stick to TotalBiscuit's reviews if I am interested about something. Anything major that might get my attention, he will 99% of the time review it, and he also covers alot of indie games which I like seeing. Last time he did 'Receiver', a game I had already been playing for a few weeks before, but his judgement is nearly always unbiased and fair, straight to the point.
Hence I don't know many bad examples, since I don't view alot of others. But certainly, I have occasionally seen the few that are just putting up a brick wall to your arguments, just to spout out great words about some product. Money money money, sigh.
