I am really looking for an answer to this. I promise to incorporate the best answer arriving out of our discussion in my site flixcatalog.com. I don't think the existing filter on imdb scores makes sense.
If you look at what nomadlist.com has done for places - I can easily figure out if I would like to visit a place or not, by selecting their emoji based filters.. I think a similar emoji based rating, that could say how sad a movie is, how happy a movies is, etc, could be useful. What you think?
How do you propose a scoring system would work where movies are scored according to your preference in movies?
