The Cat in the Hat
The fact that this candy-colored trainwreck is officially titled "Dr. Suess' The Cat in the Hat" is a savage slap in the face to the imaginative author whose work is utterly misrepresented here.
Mike Myers' Cat is the stuff of nightmares, tossing in uncomfortably adult jokes as he mentors (read: menaces) two young children.
How terrible is it? Dr. Suess' widow threatened to take anyone who tried to adapt another one of her husband's books with legal action.
