tl;dr: movie execs are blaming RT for poorer-than-expected sales this summer.
I can agree with the view that studios have become risk-averse and increasingly lame over the years, with detrimental effects on the quality of movies (originality, execution etc). That being said, I am also extremely skeptical of the utility of crowdsourced ratings, both on theoretical grounds and based on anecdotal evidence. A lot has been written on this subject, and I recommend reading the brief discussion of ratings found in William Poundstone's "How to Predict the Unpredictable" for an overview of some of the problems.
I don't think RT can be held responsible for the movie-industry serving up shit and expecting everyone to think it tastes like chocolate soufflé, but I think there might nevertheless be some merit to the notion that crowdsourced rating sites like RT may have unintended detrimental effects.
