The Last Airbender Prequel : Zuko's Story

So I got this book for Christmas finally (I've wanted to read it since it came out in 2013). But I've got to say it didn't really tell me much for a prequel. Also it was based on the movie, not the show which I didn't know about until I opened it up and Uncle Iroh wasn't Uncle Iroh. I didn't see the movie but I've heard that the character design is based upon the atrocious movie characters instead of the awesome show characters. I never adjusted to Iroh's design, but it was an interesting read. At least Azula, Mai, Tylee and Pathik all looked the same. Seeing Pathik again was actually pretty great.
