IMDB reflects popular opinion. Everyone has unpopular opinions, heck I liked the Emoji movie. Also, for some niche movies the ratings are wildly skewed since only die hard fans are voting on them. And for some movies where there are strongly held opinions, many people will pile-on and vote on them without even having seen the movie.

All that said, IMDB is a useful tool for getting read on popular opinion on movies. Also, IMDB is standing behind me with a gun to my head. Send help, please.
