To quote the article you posted: "My first reaction was semi-outrage that anyone should be allowed to tamper with this incredible series," he(Colfer) said. I'm afraid he should have listened to his own first reaction. Trying to take over a book series started by another writer seldom works. Especially when the writer was a comic genius with a very unique sense of humor like Adams was. I don't think anyone can write a book that will really fit into his bizzare, twisted universe.
