I agree that this article was butchered. Perhaps there were too many single sentence examples from popular culture, but why were they all deleted? After reading the sourcing guideline docs it's unclear to me when something can be it's own sourcefor example, the picture from Funny Games seems to verify itself well (it is from Funny Games and he is breaking the fourth wall). In any case, I think most people trying to find out information about the Fourth Wall would find the current article much less helpful than some earlier versions.
