I think the world is more infatuated with 3D in movies because it looks so amazing and is next level but 2D will always capture attention if it is done right. And television will always have a place for 2d animation. I still think it all depends on what your doing with it. 3D is just so prominent in the peoples animation hearts because that is all that is coming out in the movie world, not many people like to take risks in less popular genres or new ideas.
That's how I feel, and how our school seems to help us feel. 2d seems to have a lot to compete with now. As 3D is becoming very flawless and even better looking.
