Like I said (a million times), I was shocked and surprised by the negative reviews I would see on the web, I thought it's a great film with a excellent soundtrack score by the James Horner (An American Tail,Krull,Titanic,Troy,etc), and a wonderful blend of live action and animation; And this film became one of my favorite live action/animated films along with Disney's Song of The South (and the new Enchanted), and Arthur and The Invisibles.
The film starts with 10-year-old Richard Tyler who is scared to do anything that might endanger him, like riding his bike, or climbing into his treehouse. While seeking shelter from a storm in an old library, he is mystically transported into the animated "wonderful and quite unpredictable world of books." I love the main title sequence with the clouds that was awesome! and the mural in the library too.
