The short version
Animation cannot fix a weak idea, a wrong structure or an unclear message. It can only make them move.
What is really going on
The message hierarchy is set in the script. If two ideas compete for the same three seconds, no amount of easing resolves it.
The look is set in the style frames. Approving a direction as a still is cheap; discovering it does not work after animation is not.
The pacing is set in the animatic. Timing problems found at animatic stage cost minutes; found at render stage they cost days.
How to handle it
Write the one sentence the viewer should be able to repeat afterwards. Everything that does not serve it is decoration.
Produce two or three style frames rather than one — a single option is a decision, not a choice.
Cut the animatic to final length with temp sound before animating anything.
The takeaway
Pre-production is where the quality is decided. Animation is where it is executed.
