Yeah, i remember going to see it mostly because of 3D (which probably helped a lot in becoming one of the most successful movies ever, thanks to the novelty and higher ticket price).

But left so little impact that i can hardly remember anything about it and have no interest whatsoever in seeing the sequels.

The theme park in animal kingdom was fine

I don’t think grasping and visualizing are the same. I am sure you can grasp the concept of 3. Like 3 cars waiting on a light, or 3 slices of pizza.

If the limit was visualizing, the answer would be zero, since some folks can’t visualize at all.
