Disney is well known for taking the fairytales of our childhood, sweetening them, and turning them into animated musical extravaganzas for children. Beauty and the Beast was originally a French tale, written by Jeanne-Marie Leprince de Beaumont, but it has been translated and retold almost from the moment it first appeared in print in 1756.
Bears is a much more straightforward nature movie than you might expect. The story of a pair of brown bear cubs and their mother through their first year together, it doesn't try to escape the inevitable cuteness of bear cubs, but except for that, it does not present the life in nature as being cute at all.
The Odd Life of Timothy Green is a fantasy movie that wants to be a charming little moral fable, but that lacks emotional charge and involves one plot problem that may give you no trouble if you keep in mind that there is nothing requiring supernatural beings to have much intelligence.
