Last night I saw Harry Potter & The Deathly Hallows: Part 1 in IMAX with some friends. Man, it was intense!~ You forget this series was actually written for children/young adults. In case you're not familiar with the series - the content of this book (and movie) is incredibly dark. By Book 7, pretty much all hell has broken loose in the wizarding world!
Though the movie was 2-1/2 hours long, but definitely didn't feel it (and I'm an antsy movie theater-goer, so that's saying something). The movie was literally running from the first 5 minutes, I don't think there's been such an action packed HP film thus far. It makes me want to go back and reread the 7th book, so I can be prepared for Part 2 next year!!!
