I used to have a red (stop), yellow (consider), green (go) rating system for movies, but there’s not enough nuance there, so I’ve switched to a five star system. I’m also going to employ a half-star between three and four, and three and two.

Five is a must-see. Life changing or makes you change the way you think. There are not many movies that get this rating. There are probably fewer than 100 movies that get this rating.
Four is a should-see. I enjoyed it and recommend it, but it doesn’t deserve the highest rating. There are probably fewer than 1,000 movies that get this rating.
Three means I finished it, didn’t hate it, but I have mixed feelings about it. It’s not a should-see. These movies are usually not terrible, parts of them could even be good. Oftentimes decent movies that are too long get this rating.
Two means it’s bad. I stopped watching it shortly after starting it. Avoid. There are probably more than 100,000 movies that get this rating.
One means it’s terrible. This is an even worse rating than 2 since it means I watched it long enough to regret even seeing it.

By the end of 2026 I should have a public, sortable spreadsheet for all the movies I’ve seen with their respective rating.
