Pixar is not a theme.

Since this seems to be something most don't understand, I'll start with a question. What makes a movie a Pixar film?
Well, it is created by Pixar, and the name Pixar (or Disney-Pixar) appears in advertising and on the movie itself. But Pixar is just a name. That wasn't the case in 1996, but 20 years later, it most certainly is. Could the average guest even tell you which computer animated movies were made by Disney and which by Pixar (apart from the obvious like Toy Story and Frozen)? To prove my point, I pose another question: what makes The Good Dinosaur a Pixar movie and Zootopia a Disney Animation movie? Why would Zootopia not belong in Pixar Land? Because it doesn't have the name Pixar stamped on it?
If the connecting feature of a land is the name and not the content, that is not good. That is poor design.

Oh, but you are about to tell me there's a place called Fantasyland. I can't see the future, but I can see what you came back at
@lazyboy97o with a number of pages back, and it is sure to happen to me. So I shall explain in advance. Fantasyland works because it takes you into a realm of fantasy. It is about the content of the land, not the name.
Furthermore, the land works because it is in contrast to Tomorrowland and Frontierland. Oh, did I forget Adventureland? Sorry. What I mean is that taking you into the world of fantasy isn't the strongest theme by itself, but it becomes a strong theme because the neighboring lands take you into vastly different worlds of yesterday, tomorrow, and adventure. If you don't like Star Wars land going to Disneyland Park, you have good reason. It may weaken the contrast of the park as a whole.

So "Pixar Land" is a poor idea, I made that clear in the first large chunk of my post. Whatever they go with needs to be about the content of the land, not a name. And it should work in contrast with the rest of the park.
While asking you to agree may be a bit much, I hope you at least see my point. If you don't agree or have any objections, please explain. I'm open to what everyone has to say and would be glad to have a good discussion.
