One of the favorite things for disgruntled animation artists to do when they kvetch is complain about how sh!tty animation scripts are.
Some suck, some don't.
Frankly, after seeing some of the tripe from the 1970's and 80's, the writing for animation has gotten a helluva lot better in my opinion.
I don't think writers themselves are the major problem.
The problem comes in when they're writing crowd scenes, epic battles, and other scenarios that require time to do.
Time is what we're not allowed to have by the studios.
What thee EFF?!
This goes back to the good, fast, cheap model. Or rather, IT SHOULD.
If the scripts were less complicated, the artists would be able to adhere to the sh!tty schedules given to them. Right? Sometimes the artists are allowed to edit down scripts before they begin boarding, but some executive @$$holes want it ALL and then will edit down after the artist gets used up and tossed out like a condom on prom night.
Here's a challenge open to anyone who doesn't have their set in a jar in the attic:
Ask an writer what their favorite cartoon is. IF they have one, it probably involves something simple: one to two characters doing something non-complicated. Hopefully a light should go on over their heads. If they kvetch about how execs want more-more-more, remind them:
PICK TWO OUT OF THREE.
That applies to writers, too.
What would happen if writers and artists worked more in tandem to get the execs heads out of their ADD-riddled @$$es?
