Not every show or movie is for everyone and savvy viewers research the movie or show they are interested in before actually watching it. This little bit of research actually stops them from making too many mistakes and wasting an hour or two watching something that they would prefer not to under normal situations.
Of course, it does help to pay attention to the Netflix reviews. Sometimes the reviews are obviously written by people biased against the movie and others are just poorly written. In general, look for details, try to avoid political diatribes disguised as reviews, and look for reviews that discuss what actually happened in the movie. By doing so you should should avoid the bad reviews and find out whether or not the movie or show really is for or should just be passed over.
