Adaptations of books are always difficult. Should you do a straight up adaptation or should you only use the book as a guide? And even if do you a straight up adaptation, how do you handle the things that work well in books but simply don’t translate to film? These are all common problems, but none of these affected The Hobbit. Indeed, The Hobbit did it all perfectly.
The one downside I would say with The Hobbit is that the animation is a bit stark. It’s a lot like Charlie Brown where a couple squiggles pass for a battle. But ultimately, that’s not much of a flaw because the story is so strong and the rest of the animation is so spot on. If you haven’t seen this one, you absolutely should.
