The Secret of NIMH is a 1982 American animated fantasy adventure film directed by Don Bluth in his directorial debut and based on the 1971 children's novel Mrs. Frisby and the Rats of NIMH by Robert C. O'Brien. To save her ill son, a field mouse must seek the aid of a colony of rats, with whom she has a deeper link than she ever suspected.
In the book, Jeremy is a young, naive, and cowardly crow who likes shiny things and was at first caught in his own string and Mrs. Brisby manages to free him before Dragon appears and he thanks her for her help. When they next met, he has an aluminum sheet and asks him for his help. He shows compassion for her and offers to take her to The Great Owl.
In the afternoon, Jeremy came to Mrs. Frisby's house to take her and he meets Mrs. Frisby's children, Teresa and Martin, except Cynthia who she is afraid of him, and he later takes her to The Great Owl.
In the film, he's shown to be a clumsy, funny, and comical crow who meets Mrs. Brisby and they both encounter Dragon the Cat and Jeremy fights off the cat and tries to save Mrs. Brisby but failed, and he eventually manages to save Timothy's medicine.
Later, he flies Mrs. Brisby to see The Great Owl and later gets asked to watch her children which he gets apprehended. In his next appearance, he was seen hiding in a pond and was told by Mrs. Brisby to get all the string he can to form a lever and pulley system to move her home. In the end, he wonder what he will do with all the string and gets crashed into by a female crow named Miss Right and makes a love nest with her and flies off with her in the end.
In both adaptations, Jeremy is shown to be kind, compassionate, and supportive and always helps Mrs. Brisby with her problems. In the book, when she untangles her, he thanks her. He is shown to be compassionate to Mrs. Brisby's kids too. He even suggests that Mrs. Frisby should seek help in moving Timothy from an owl who dwells in the forest and takes her there.
In the film, while he became more clumsy and comical, he still retains his compassionate and supportive personality and even fights off Dragon and tries to save Mrs. Brisby and saves Timothy's medicine and gets all the string needed to form a lever and pulley system in order to move her home.
In the sequel, he flies Timmy and Jenny to NIMH and manages to save Timmy and Martin from falling to death.
He has none. He is very friendly, compassionate, and helpful and never has any negativity in him.
I don't know, I think he should.
