I thought it would be helpful to spin this off from the Crash thread. Everyone has different criteria for rating movies -- which is quite fine by me -- and I figured it would be helpful if people explained their methodology. Me, I use three stars as the baseline. Three stars means that I found the movie entertaining from beginning to end. Well, entertaining may not always be the right word -- you may want to substitute gripping for a drama or informative for a documentary -- but regardless of adjectives it's a good movie. Moving up one notch, four stars means a particularly good film that is well-written, features excellent acting performances, and is well-directed and produced. This is a movie I'm going to want to see again. At five stars are my all-time favorites. I should add that as far as historical evaluation goes it's in comparison to movies I've seen and liked not to every movie ever made. So films like "Donnie Darko" and "Monty Python and the Holy Grail" are going to get five stars because they're MY all-time favorites not because they are objectively the greatest films of all time. Moving in the other direction, two stars is a bad movie that has some redeeming quality - perhaps a dumb comedy with quotable one-liners or a drama where one actor puts in a memorable performance. One star films have only one redeeming feature in that I was able to watch the movie end to end without leaving the theater or turning off the TV. I also reserve the right to award zero stars for something that is unwatchable. Half-stars grant a little nuance in between these rankings. I tend to be highly-selective in the movies I go see so I tend to award a lot in the three to four star range since I just don't go see the movies that would get lower ratings. So that's me, how about you?
