too add to this...
Executive producer Christopher Meledandri said of the change, "The minute you make the Once-ler a monster, you allow the audience to interpret that the problem is caused by somebody who is different from me, and it ceases to be a story that is about all of us. Then it's a story about, 'Oh I see, the person who led us into the predicament is not a person. It's somebody very, very different.' And so it takes you off the hook."
Let's not forget... 22 page kid's book to 90 minute movie. And this is a Dr. Seuss book with a pretty intensive plot, such as it is. The TV special added only so much (musical numbers and cartoony gags with the demolition machines), and that barely made it a 22 minute special. Which is
THE problem I have with making kid's books into movies. You need to tell a story that
wasn't there to fill out a film's time. Often, you need more story than the book had in the first place, sometimes
double that amount. Shrek managed to do it almost flawlessly, but not without making it its own story. Most of them aren't that successful. Some incredibly terrible to the point they're in name only.
I have yet to see this film, but Horton was padded out with a fleshed out storyline for the Whos, especially the "emo" kid who yelled the loudest "YOP!" They gave the Yop kid an
entire backstory. Barely a sentence got an entire backstory. Not to mention Horton's completely random Doug/Arthur-esque fantasy cutscene.
Yet, movies based on huge novels get stuff cut out and condensed to the point where Harry Potter got flack for glazing over a lot of details. And now The Hobbit's getting flack for being stretched out to 3 movies (the other film trilogy got a movie per
book and was heavily condensed) to be able to tell the entire book as a movie. It's kinda no win. And movies based on books are as old as movies.
