I love this game! I remember everything I read, and I love Harry Potter, but this game can be difficult sometimes. My friends who have only seen the movies can even answer questions, and my little brother and his friends love playing it.
My only complaint would be that sometimes the movie clips are too long, especially for the die-hard Potter fans, who have seen all of the movies enough. The questions on the clips sometimes do not go hand in hand also.
One other complaint is that if you are afraid of some of the darker elements of Harry Potter, you might get a little creeped out by the dark music and colorings. My younger brother has closed his eyes on two occasions, so only younger kids MIGHT be a little scared.
Other than that, there is nothing wrong with this game. If you love Harry Potter, either book or movie form, or you want to learn more about it, this game is perfect!
