While the parent is right in stressing the importance of the review phase, which is a filter to decide whether we will ever see a candidate paper or not, it is indeed the case, as the OP posits, that there is merit in extracting the context in which a citation is used, which has been termed "citation polarity".
For example, 'Chomsky (1969) was entirely wrong when he said that “it must be recognized that the notion of 'probability of a sentence' is an entirely useless one, under any known interpretation of this term".'
There are Natural Language Processing methods and tools to extract the citation polarity. Researchers like S. Teufel have used citation polarity and other methods to analyze publications ("rhetorical zoning") and to create maps of the published literature: https://www.cl.cam.ac.uk/~sht25/az.html
A scientific literature search engine (Semantic Scholar, CiteSeerX etc. - sadly Microsoft Academic has recently been discontinued) can benefit from such knowledge; for example, PageRank can be modified so as to incorporate citation polarity in the random walker model that underlies it. Think of it as adding a "dislike" button to a system that already offers a graph with "like" button relations.
