Confirmation Bias
I think I've seen a few cases around where this seems to have happened. Just keep in mind that confirmation bias exists and can influence your thoughts (*tinfoil*). Just because, say, a review is gloomy/glowy does not mean it's (un)biased.
In psychology and cognitive science, confirmation bias is a tendency to search for or interpret new information in a way that confirms one's preconceptions and avoids information and interpretations which contradict prior beliefs. It is a type of cognitive bias and represents an error of inductive inference, or as a form of selection bias toward confirmation of the hypothesis under study or disconfirmation of an alternative hypothesis.
