At the beginning, Harry is shown back at his Aunt & Uncle's house but now he actually has a bedroom. I guess his muggle family is a little worried about pissing off the new wizard in the family, but not so much to stop treating him like a servant. Then we meet Dobby, an elf (man, this series does not treat it's non-human species prettily) who wants Harry to not return to Hogswart. It's dangerous y'know. Of course Harry refuses which causes no end of trouble. Of course he goes back to Hogwarts and of course there is danger and of course Harry and his friends cannot help but get mixed up in it.
The "episode" is all about the danger that lurks within the halls of Hogwarts, something that is presented not only in the lurking shadows of Voldemort but also in seemingly random elements of the school itself. Magic, whether light or dark, seems to come with a dangerous element that cannot be avoided. Things are discovered and deemed dangerous, but not destroyed or removed, just controlled and/or hidden. Also, this movie introduces the idea, which gets worse and worse, of the political involvement in Hogwarts and wizard affairs. Not shown as dark or light, they are meddlesome, controlling and insidious in only a way politicians can be. It seems, even in a world where Dark and Light can have capital letters, politics is its own form of evil.
