I am interested in developing a consistent rating method for movies (and tv series).
I found https://www.reddit.com/r/movies/comments/aeb0ce/how_do_you_rate_movies/ there are some nice comments/ methods and I think I may not achieve a consistent rating method for myself. Simply because I may think that some cool and innovative technique is cool today won't be cool tomorrow anymore.
Moreover, I don't like a movie like Avater anymore, which I liked 14 years ago, my taste is different today. And Avatar isn't as impressive today like it was 14 years ago. Should my disliking of the weird sci-fi characters influence the rating or should I look at professionally and rate it on what the movie ought to be.
On a good day I may sit through a lengthy movie, on another day I won't.
What's your take on it?
I have a very complex rating system that I apply to every film I see. It ends up as a score out of 100, built up from scoring points in different categories.
I subdivide into 3 groups first, Enjoyment (50pts available), Quality (40pts available), Rewatch-ability (10pts available). Most of these are subdivided in some fashion, such as Quality: Writing, where up to 5 points can be awarded.
Here are 3 examples of scores as I record them.
The Fellowship of the Ring 92 (E48 Q36 R8)
Mary Poppins Returns 72 (E43 Q25 R4)
GI Joe: Retaliation 42 (E23 Q17 R2)
Most films I see score above 40, so it's a fair argument to say there is a dead zone in the rating system, but in reality a film should reach a bare level of quality so scoring under that threshold is a real indicator of a something really shit.
Update: Regarding your Avatar question. My system allows an individual's personal level of enjoyment to be scored in addition to the fundamental quality in a given film, so even a film like Avatar that you don't like as much now will still be able to get a respectable score from the other categories.
