I think reactions to the notion of the Harry Potter franchise can be divided up into two camps. There is the camp that is unamused by the idea of Harry Potter and all that it represents, and there is the camp that is absolutely fascinated by the wonderful world of Harry Potter, as it has been created by J.K. Rowling and the Harry Potter movies. If it's not obvious by now, I'm a member of the latter camp.
Even though I love the Harry Potter movies to death, Harry Potter and the Deathly Hallows Part 1 was quite severely boring for me. There was some action, yes, but there was far too much scenery. I just saw Harry Potter and the Deathly Hallows Part 2, and may I just say, it was well worth the (unfortunate) wait. Part 1 left off from the story prematurely, and it was rather satisfying to have one movie tie up not only the remnants of the Deathly Hallows theme, but also the movie franchise as a whole.
It must be said that this movie will be enjoyed and relished the most by such dedicated fans of the films as I am. However, if the Harry Potter movies are foreign to you, by all means, watch the very last film and try to understand why so many people find the films so appealing. The Harry Potter films make magic cool. Sure, wands may seem to be a bit of a wimpy kind of weapon at first, but you get used to it. It's especially cool to see wands do things like light up the sky with lightning and thunder, toss bad wizards out the windows of Hogwarts in slow-motion, and connect with each other in a fiery blaze.
I definitely recommend putting watching Harry Potter and the Deathly Hallows Part 2 on your to-do list. In particular, for the Harry Potter fans, it's such a relief to have a chapter of your life close on you in a most reaffirming way, and to have a lingering feeling that somehow, after the destruction of the fictional Lord Voldemort, the world is a safer place.
