...After all, THEY know how to make a movie.
Though I do wonder what Bolt would have been like if it was made as it. But they did totally salvage the Tinkerbelle movies, I hear.
Its hard to say.
But I'm positive that any creative changes made to the original idea were done for the good of the story. John Lasseter feels that story is the most important thing. He doesn't mess around.
Clearly it was determined that the early story was not going in the right direction, so changes had to be made.
This isn't the first time that this kind of creative/director change has happened. It also happened early on with Pixar's Ratatouille.
In the end, BOLT was a good movie and that's all that matters.
I'm very glad that John Lasseter was the executive producer on the film.
As for the Tinker Bell movie. Its true. The movie was very close to being a disaster, as evident by the deleted story reels on the DVD.
One deleted idea had Tinker Bell drowning her sorrows by stuffing her face with basket after basket of muffins.
