Worst type of reviews are biased ones which don't focus on what is important, the product that is reviewed.
The developer who creates the game shouldn't have any impact on the review, if it is your main point for why a game is bad then you are horribly wrong because what the developer has been doing shouldn't have any impact for how the game is in its current state. I see a lot talking about how good the game is and then dropping a poor rating because of how bad the developer seems to be, which should have been left out from the equation because it isn't important for rating how the game currently is. You can't simply give a game a good or bad rating for who created it, content (i.e. the game itself, nothing around it) is what is important and should be focused on in a game review.
