Nobody has seen the 2009 Version, EXCEPT maybe the people who went to the February reviews. But we know it's real because the 2009 Version is the version that was promoted/marketed before July 1.
You can buy the movie's Novelization (based on the 2009 script) and you'll pretty much know everything about how much better the movie originally was. And we've also seen
pictures (movie screenshots) which prove that Shyamalan filmed his original 2009 draft.
The 2009 version is better because it DOESN'T have Katara narrating all the time. Also: less expositiony dialogue (+) more Sokka-humor (+) Katara loses her necklace and Aang gets it back from Zuko (+) Zhao hurts Aang & Zuko more personally (+) the Kyoshi warriors save Sokka and Katara (+) Sokka meets Suki (+) Katara has personal training in the North Pole, and several other things that we didn't get to see in theaters.
