Are minecraft 3D animations hard to make?

Some animations, such as "stick" type, are relatively easy to make.
GOOD animation (3D), on the other hand, are extremely complex to set-up and require years of training.
The simple animation of the terminator female, going from woman to robot, and lasting only 8 seconds in the movie, took 4 months to make by a team of professionals!
There's NO easy software for animation and, if they are, they are crude and gave poor results.
Minecraft is just a little bit better than basic. If you find that complex, then go no further, or be prepared to make animation your full time profession!
