IMDB is a popular movie and television rating website, but how reliable is it? Reviews from IMDB can be from anyone, and the ratings are calculated from the average of these reviews. This means that people who are more passionate or have a strong opinion may skew the ratings. In addition, IMDB also allows people to delete reviews, which could influence the rating. Overall, while IMDB ratings can be useful, they should not be used as the sole source when deciding whether or not to watch a particular movie or show.
