you are making a strawman."the algorithm recommending me stalker is proof that Criticker users are pretentious and rate films highly solely because they're considered artistic--"
I do not say people at Criticker are dishonest, but there is a difference between rating due to the degree of one's subjective enjoyment and rating due to the objective quality - both ways of rating are equally valid - depending on what is the goal. At Metacritic (which would have been a much better example for me to use than Rotten Tomatoes) objective quality of a movie would be more relevant compared to the subjective enjoyment of the critic. The objective quality would also be the most relevant to rank by at Criticker if one is supposed to use it to search for movies with objective high quality (and as I said, the name Criticker can in some way suggest this). And as I pointed out, some comments in this thread (and other threads) show that there are users who do make their ratings based on this!
And if some people (like me) follow a rule when ranking movies that says "I can see that Godfather is a marvelous piece of art (and here I intentionally have picked a popular movie!) but it bores me to death to watch gangster movies so I give it a low rating" and if there are other users that are also bored but give it a super high rating since it is very well made, then probable scores will suffer from these different rating strategies.
