Yeah, it really depends on why you are evaluating these scores.

If it's simply to answer the question, "what will the wife and I watch tonight?" and you're presented with a algorithmically limited set of options based on your viewing habits and your up/down votes, yes, I think scores are a "good enough" blunt instrument.

If you want to explore the work of a particular director, genre, theme, period or actor but don't want to just watch all those films chronologically (or by only viewing "the blockbusters") then reading a bunch of reviews will help A LOT. The scores in that scenario would then merely be trite factoids.
