I would argue that Fantasyland was never designed to represent a specific historical environment the way that Main Street or NOS do. It's all fairy tales and fantasy, not history.Do you want evidence of this? Take a look at Fantasyland. Is there theme or time period? Sure, we're in the middle of an architecturally rich Bavarian village - are the rides contained therein (Peter Pan, Snow White, Alice, Toad, Pinocchio) fully reflective of the medieval time period or the theme of the land?
Integrating something that occurred before a specific time period is, to me, a much different matter than adding something modern. Abraham Lincoln is probably the most popular and culturally resonant President we've ever had, and his popularity at the turn of the century was through the roof. While his physical presence on a Main Street of the early 1900's isn't exactly historically accurate, it would be much different if it were "Great Moments With Mr. Clinton" instead.Look at Main Street. Is attending a speech presented by Mr. Lincoln really consistent with the turn-of-the-century time period of the architecture, or the theme of American patriotism?
If you have an environment themed to the 1940's, CG characters aren't exactly the best fit. And again, I see much of this expansion/do-over trying to connect the park to Walt Disney. How does ignoring his own personal legacy in favor of Pixar characters accomplish this, I wonder?So in that sense (along with the Frontierland example), why would it be errant to see modern Disney characters referenced in the Animation attraction? Or would that be too much of a stretch?
The specific time period is unspecified, but POTC effectively begins in the bayous of New Orleans of the mid 19th century, and HM is set in a haunted Antebellum Mansion with kept grounds and butlers. They are both representative of a specific themed period environment, and aren't supposed to take place in the present day.
