Great companion book to a great "Book One!"
I really like that the creators have been so heavily involved in the comics and art books from Dark Horse, and as such, I want to own all of them after looking at this gem!
The artwork is beautiful, and it's awesome reading little anecdotes from the series creators. Did you know that polar bear dogs are feared by the Water Tribes, but Korra met a lost cub when she was little and now she has Naga!? All of the notes add to the universe of the series and make you feel involved in the show. As a fan of the original series, I'm now a little older and can really appreciate the work that goes into entertaining people, so this book is exceptional at presenting that feeling.
The book is separated into a few sections, focusing on early development, each episode of the first season, and extra artwork created for promotion such as the DVD cover. I love being able to look at the concept art and notes and then watch the series at home. I highly recommend grabbing the Blu-ray version of the series. It has audio commentaries for each episode, so you are really being thrown into the universe of The Legend of Korra!
I highly recommend to everyone who is a fan of the series!

BEST ART BOOK (GREAT GIFT FOR Legend Of Korra FANS)
It is a beautiful book. It was everything I hoped for, but it was bigger than I expected. (I didn't see the measurements/size...oops) The artwork inside is incredible, the detail and effort that was put into this book is amazing. I am a huge Legend of Korra fan, so I was a little nervous when I bought the book. I had my doubts but when received it I was so pleased with it. I could not be happier with this book. I highly recommend this book to anyone considering it to either give to a friend or to buy for personal use.

A good one, albeit not a perfect one
It is a comprehensive look into the series with lots of wonderful art.
I felt that it was thinner than the previous book from the Avatar series but I'm not talking about the length of the book (I know this one has less pages an only covers one season) but rather about the "insights" into the creative process. While the previous book felt full to the seams and you could feel that there was a lot of important material that didn't fit, you also felt that all the material that did was included was the best. In this one for Korra, you feel that there were many important things left out that should have been included and there are some things that were included that doesn't feel as important...

Everything you wanted put into a art book
I loved this art book. It showed me basically everything I wanted to see from back drops used and unused, old character designs and how some things came to be or what they were inspired by. The commentary is great though rarely confusing (Ex: at one point they commentary refers to a picture in the top right but says "As you can see by the design in the middle" the middle being something completely different) I feel like this book is a must for fans and people interested in the art of the series alike.

This is how you make an artbook!!
It's so awesome to open an artbook and see every stage of the character and how it all came together. It's always fun and interesting to know how Korra was made, and why whe looks the way it looks. It's really cool to read the different ideas that came up for a certain character and why they decided that a certain design worked better than the previous ones! It's also really interesting and delicious to read about how they inspired themselves in known architecture to create the environment in this tv series.
I simply loved it and I'm excited to know that I'll be buying the other Korra artbooks!!!
