I oversimplified for comedic effect, but the animation was just terrible in that movie. All of the character movement was awkward and didn’t feel natural at all.

The thoughts were, what could be more realistic than the motions of real actors? And the answer was: nearly everything. Sure, we use motion capture, but we’ve mixed it with traditional animation theory and fine tuned it to work. Far from the awkward mirroring they did in FF.
