If you haven't seen the Harry Potter films yet you'd better hurry up and go to watch them before someone ruins the ending for you.
The films are very good and there's 8 of them. So you really have no excuse for not watching a piece of film history. And a piece of literary history too.
If you are 1 of those people who have been living in a cave recently and haven't seen the Harry Potter films then evidently there is something wrong with you. It's past time you've seen them. If you don't someone's grandmother is going to ruin it for you because their grandmother will have already seen it and you haven't.
If you're 1 of those people who think that there is nothing that Harry Potter has to offer for you, I'm sorry, pull your ignorant head out of the sand and go watch it already.
