What are your thoughts on "Hatchet" by Gary Paulsen?

I thought it was a very interesting book. True that it did drag on some parts, but the concept was great. Makes you think if you would have the skill and cleverness to survive in the wild like he did. I also saw the movie as well, but didn't really think it did the book enough justice. Especially since there's not much dialogue or anything to represent the characters thoughts.
