You Tell Me...What is Your Favorite Adaptation?

Since I've been taking a little break on the writing front for a couple of weeks, I've been spending a lot of time reading and watching movies. Stayed up late last night watching the making of Harry Potter (very interesting :) ), I Am Number Four is now on Pay-Per-View, I've watched the Breaking Dawn trailer a zillion times (can't wait! If you haven't seen it, our lovely Kristal has it on her blog), reread the whole Sookie Stackhouse series and am anticipating the start of the new True Blood season in a couple weeks (mostly because of yummy Alexander Skarsgar/Eric).

 (yum :D )

There are so many good movies out there based on books. Some that stick pretty close to the books (like Harry Potter and the Twilight films) and those that are more based on the storyworld and characters but add in their own far-fetched storylines (like Sookie Stackhouse/True Blood).

So I'm wondering....which book-turned-movie is your favorite? Are there any out there that you absolutely love...or hate? Do you prefer movie adaptations to remain as true to the book as possible or are you open to different interpretations of your beloved characters and stories?
