Common Sense Note
Parents need to know that, as has been the case with each succeeding movie, Harry Potter and the Order of the Phoenix has its main characters taking on bigger challenges, with darker themes and more intense danger. The climatic battle scenes with "You Know Who" and his minions are downright frightening. Spoiler alert: There's a very upsetting (but bloodless) death of someone near and dear to Harry. As a result, he grows even more introspective and angry. At the very least, he does enjoy his first kiss (no spoiler to Potterheads), and Ron and Hermione continue their flirtatious bickering.
Sexual
Content
Harry and Cho kiss; Ron and Hermione continue their thinly veiled flirtation through bickering and glancing at each other.
Violence
Scary images of Dementors, Death Eaters, and Lord Voldemort. Angry centaurs drag a character away. Professor Umbridge severely punishes Hogwarts students using a method that feels a lot like torture. A character is attacked by a large snake, with somewhat bloody results. The depiction of the battle at the Department of Mysteries is intense, and one key character is killed (though not in a gory way). Harry is painfully inhabited by the Dark Lord; he is also very angry during much of the movie.
Language
The word "bloody."
Social
Behavior
Harry's friends bravely agree to practice defensive spells to help him ward off Voldemort and his evil cohorts. In particular, Ron and Hermione refuse to let Harry go up against 'You Know Who' alone. Harry, his friends, and the Order of the Phoenix members act in a courageous, selfless manner. The movie's key lessons are that it's your choices and the actions you take that define you and that friends, family, and love make you more powerful than even the strongest evil.
Consumerism
No product placements, but the film franchise includes a ton of merchandising deals, toys, and other tie-ins.
Drugs / Tobacco /
Alcohol
Harry and his friends meet in a run-down pub in Hogsmeade, but they don't drink anything.
