If evil cannot create things in Tolkien's mythology, how did Melkor create dragons?
In The Hobbit (book), goblins and orcs cannot move in daylight. But in the Hobbit movie, orcs are seen pursuing the dwarves down a river in broad daylight. Did Peter Jackson just ignore the daylight-averse quality of the orcs as Tolkien originally created them? Is it a mistake? Or am I wrong?
