Movie Grading Scale REVISITED

I've decided to view my grading scale as something that is constantly evolving. The finished product will always be in the header, and will remain on the BLANK-out-of-10 scale, but how it gets to that scale needs to be something more than just "Oop, that was a hoot, NINE T'S!" on my end. So sayeth me.

Why?

That's why.

So here's how it will work: four (for right now at least) mini categories that will be on the mini-t scale. I will add up the total of mini-t's and then divide by the number of categories. Each category is worth 10 mini-t's, each mostly independent of the others. Aaaaaand here are your categories:

Cast - 10-mini-t's

How did they do? Did I believe them? Where they enjoyable? Did they perform their craft with gusto and fervor, or did they phone their performances in?

Story - 10-mini-t's

Was it a good story? Did I willingly suspend my disbelief, or did it engage me in spite of the actors and director?

Director - 10-mini-t's

How did he do? Did he take the components above and utilize them fully? Anything particularly visionary in his approach?

General Enjoyability - 10-mini-t's

This scene was awesome...

This is a little tougher to nail down: it's my wild card. If I liked the movie, in spite of my self, this is where it will come through. If everything was terrible, but there was SOMETHING, something I can't really quantify that made me like it, this is where it will show. On the flip side, if the above were all great but the finished film just doesn't jibe, becoming something less than the sum of it's parts, that'll show here too.

Final Grade: Cast+Story+Director+General Enjoyability/four=number of T's

So there you go. We'll see how it works out.
