Regarding TSL's scale inconsistencies:
I do agree that it would be
ideal to have a land where everything were built to scale. Everything appearing to have grown by a consistent rate would definitely better foster the illusion that we are shrunk to the size of a toy. However, building everything to scale would be a much more complicated undertaking than many people on here seem to realize. In fact, in an outdoor land, the shrunk-to-a-toy illusion is just about
impossible to implement - Disney has no control over the size of the clouds, for example. They theoretically
could create thousands of tall, thick artificial blades of grass, but I'm not sure that would make for a very pleasing aesthetic. Perhaps Disney could have instead built an
indoor land, themed to "under Andy's bed," but that would have been significantly more expensive (though I do think it could have been very cool). There would also still remain several scale inconsistencies, such as with the merchandise, food, and toilets (human-sized hot dogs and swimming pool toilets, anyone?
). Another alternative would be to ditch the shrinking-theme and have the toys be toy-sized - while this would be much more authentic, it would make for a pretty lousy experience.
I think a lot of the negativity surrounding TSL's theming stems from the land's unenviable position of being sandwiched between two ultra-immersive lands in Pandora and SWGE. While those lands are meant to make you feel as if you were transported to a different place/time, I don't think it would be fair to hold TSL to those standards, as we certainly don't do so with the rest of WDW. We are supposed to be under the sea in the TLM and Nemo rides, yet nobody seems to mind that we have no trouble breathing and don't get wet. The ToT ride-vehicle is meant to imitate a service elevator, yet they contain rows of seats with seat belts. The list goes on...
I think the best way to relate to TSL is that it is simply a land built around the popular Toy Story IP. The idea that we are in Andy's backyard and shrunk to the size of toys is just meant to give some context to the land - this helps to explain why our favorite TS characters appear so large and why they are all outside. If you look at the land through this lens, the scale inconsistencies are a lot less troubling.
