My favorite film is Harry Potter. I love it, because there are a lot of magic things. My favorite character is Hermione Granger. She is smart and calm. My favorite part of the film is number 2. My un favorite character is Draco Malfoy. I don't like him, because he hates Harry and his friends, he is doing a lot of bad things. I also don't like lord Wolan-de-Mort. He kill's people. He killed Harry's mom and dad. But the film is good, I love it!
