Lecter's point is that beyond doing an entire survey of every person across north america, he has provided you alist of links from where we has been able to provide some group concensus on the film. you may not consider it as enough but that is what he can offer you.

To argue your point, either provide places from where he CAN give you data to prove his point or instead, prove your point by providing a list of links as well, that support your argument. Because as it stands right now, it seems lecter's opinion on the quality of the movie is closer to the consensus on how people feel about the film, even if you do think that the sample size is very small).

Even if you could survey every person in the world who's seen a movie, it still would not determine the movie's quality. It remains a measure of popularity.

The quality of artistic endeavors, such as movies, is not quantifiable into "data".
