This is a legal question. At least in the US, parody and satire fall under the fair use umbrella of copyright law. A remake requires permission if the material being remade is copyrighted. You can't remake Star Wars without permission as the story and characters are protected under copyright and trademark laws. You could remake a Sherlock Holmes story ...
Remakes need permission because they are directly copying the idea. While parodies are in most cases directly opposing to most of the ideas in the movie / books. Furthermore this is a case of freedom of speech. People have the right to say what they want.
Parody does not need permission because it is protected under "fair use".
