Is IMDB Movie Ratings really objective?

For many years I collected films. Films of the different countries, the different directors, different years. In the beginning it were films on VHS, then on CD, then on DVD. A lot of films I have recorded from the TV, much - have downloaded on the Internet. When has gathered Impressive collection, I have decided to compare it that it would be possible to name "the World collection of film masterpieces". I’ve referred to different sources of the information in a network on this theme, first of all, to IMDB, and has found out that in Top-250 IMDB there are no Soviet or Russian film! It speaks, ostensibly, action of the special formula used for calculation worthy to be included in this list. This formula uses two constants, i.e. identical to all participants, and two variables, namely: quantity of voters and an average evaluation.

And so. According to the same IMDB for a film of Otto Preminger "Anatomy of Murder" (1959) 16,992 "voters", for Andrey Tarkovskiy’s film "Stalker" (1979) - 21,458 "voters" have voted. Both films have received an identical average rating - 8.1. But the Anatomy is included the top list is (235 place), and Stalker is not! And there are many similar examples. My question is: Whether it is possible after that to consider ratings of this site really objective and build on their basis any databases?
