I wouldn't call it "trash", but it comes with some political bias and personal vendettas. The reason for both is that the entire wiki probably has about dozen editors, some of them way more powerful than others. So you might think that "wiki = something edited by lots of people", but for many topics there was one person who decided whether something was okay or not and wrote the article accordingly, and everyone else only added details afterwards (or disagreed and was banned). From my perspective, the greatest problem is the local cultural norm that once you decide that someone is a bad guy, it is allowed (even encouraged) to exaggerate about them, and complaining about exaggerations can get you banned. Which means that when a mistake is made, it becomes very difficult to fix it, because of course after the exaggerations anything can look stupid.
