The Speed system: a metric system of rating movies

I've always had problems with the usual methods of rating movies, either out of five stars, or thumbs-up/thumbs-down.  There seems to be no real rhyme or reason to these systems.   And I've noticed that, when I use them, there's very little consistency to my own ratings.   I tend to rate an enormous number of things 4 stars, and almost nothing at 1 or 5 stars. In college, a group of friends and I tried to make a system where we started with the smallest possible unit of a good movie.  In other words, a movie which was in fact a good movie, but only barely so.   Any less good, would be no good at all.   In this way we could distinguish the quantum of goodness, and everything else could be based on that. The first movie that came to our minds was Harry and the Hendersons.  But, we couldn't find any good way to name a unit of measurement after Harry (Harries?), so we kept thinking.   Finally, we settled on Speed. So, we built a system whereby every movie is rated in terms of how many times better than Speed it is.   The original Star Wars movie, for example, is 147.   Live Free or Die Hard is 2 Speeds.   Movies which are actually bad are worth negative Speeds. The problem with this system is that it has all the problems of the normal star rating system, but twice as much so.   It's arbitrary in how the movies are rated, plus any random person will certainly disagree with me about how good Speed is (since everyone has unique opinions).   So, you might give Stars Wars a mere 50 speeds, either because you think Stars Wars is one third as good as I think it is, or because you think Speed is three times better than I do. So, I still keep the Speed system around.   It's useful in some ways -- mainly in showing that a truly excellent movie is much, much better than one which is merely good.   But, I've moved on to a system based on recommended actions.
