you put sound and music as 10% of the overall grade -- Holy Crap!
Music and sound are the most important things in a movie for me, so in my life it works for about 50% or more. I can watch TRANSFORMERS, TRON or even STAR WARS over and over, strictly because of their scores and sounds.
Remember, sound is half of the picture.
Again, each movie is different, so you would pick the categories that are important for it. Perhaps, you could have "Scare Factor" for horror or suspense, or as I mentioned, Choreography for a dance or Martial Arts movie. The movie EVIL DEAD is brilliant for its camera work and it should be noted as a 10/10 for all the new moves it pulls off.
If you have a TERMINATOR or LORD OF THE RINGS, then the Visual FX category is crucial to the score. Each category shouldn't just be graded, but explained as to why it got the grade. Once the review base is built up, you can make logical score comparisons. There would be examples of movies that get the high and low in particular categories. Some examples could be:
SHAWSHANK REDEMPTION 10/10 for Writing.....................PLAN 9 FROM OUTER SPACE 1/10 for writing
STAR WARS 10/10 for Sound and Score.............................DRIVE IN MASSACRE 1/10
GODFATHER Part 2 10/10 for Acting...................................MARS NEEDS WOMEN 1/10
THE CELL 10/10 for Cinematography.................................GALAXY INVADER 1/10
BLADE RUNNER 10/10 for setting/backdrop.......................FRANKENSTEIN VS THE SPACE MONSTER 1/10
RETURN OF THE KING 10/10 for Visual FX...........................SANTA CLAUS CONQUERS THE MARTIANS 1/10
THE THING (1982) 10/10 for Makeup FX.........................................ROBOT MONSTER
THE BOURNE IDENTITY 10/10 for Editing/Pace................................EMPIRE (Andy Warhol) 1/10
CROUCHING TIGER HIDDEN DRAGON 10/10 for Choreography.......UNDEFEATABLE 1/10
EXCALIBUR 10/10 for Costumes.............................................ESCAPE FROM GALAXY THREE 1/10
Did you enjoy watching the movie, or not? That's all that matters.
No, it's not all that matters, because I've learned to find worth in almost any movie. I enjoy most movies. Often, I have to explain why I like a movie that so many others didn't, so I've learned to be specific. For example: I've seen the bomb, SUPERNOVA, at least 7 times. I really like the amazing miniatures, sets and the chemistry from Spader and Bassett.
However, I agree that if......if I was ever to use this system for reviews, I would have to include a biased opinion to go along with the breakdown. For example: I didn't like SUCKER PUNCH, but it would score high on the technicals. So, I would probably do it like this:
Directing - 4/10
Wonderful visuals and lots of fancy moves that don't really matter because the director didn't make me care for the characters or situation.
Writing - 2/10
INCEPTION this is not. SUCKER PUNCH has fantasies within fantasies, but there was very little connect or stakes.
Acting - 7/10
There was a decent cast and it is nice to see Scott Glenn back in a movie, but it is all overshadowed by style. There is not a lot for the actors to work with. On the other hand, no one was bad, either.
Cinematography - 9/10
Some beautiful shots and nice style in this.
Editing/Pacing - 8/10
This moves along fairly well, so I'll blame any drag on the writing.
Visual FX - 9/10
Some state of the art on display in this. The movie's strongest point.
Sound/Music - 7/10
Great sound effects, but I can't remember anything special or captivating about the music.
Entertainment Value - 7/30
SUCKER PUNCH is absolutely stunning to look at, but I've played many video games that had far more appeal. I thought the movie was dull and soulless and did not connect the viewer to the characters.
Technical/Creative score = 53%
