The related user lists for a specific movie has become useless to find similar movies to watch. Even if the movie is very special (for exemple, campy superhero movies from the 60's), the related lists are mostly massive lists such as "movies I watched" with 3000 titles in it. 95% of users lists are not interesting because they are just useful for teh person who created them. There's no common theme, genre or ideas. The problem with the user lists is that they are public by default, so the list section is populated with useless list like "movies I have on my iPhone". And it deosn't help that there's no option to search lists by keyword.
