Corrected entry: In the beginning Aang didn't introduce himself to Sokka & Katara. They both found him at their home, which is the southern water tribe, which is in a different place in the world. Normally you don't wait until you arrive at a different place to introduce yourself.
Corrected entry: It is mentioned several times that only the Avatar can go to the spirit world, and speak with the spirits themselves. Yet, Commander Zhao, and several other humans, are able to not only find the Moon and Ocean spirits, but Zhao is even able to kill one of them.
Correction: There's a dfference between the spirit world and the spirit's forms in the real world. It is stated in the film that the water and moon spirits in the cave are spirits who have inhabited regular bodies on Earth. The spirit world is where the dragon spirit exists and where the spirits have real power.
Corrected entry: When Iroh is angry about the moon spirit getting killed, he creates his own fire. It is clear that his flames are licking the leaves of the tree, but it does not ignite.
Correction: How is this a plot hole, or even a mistake? He didn't introduce himself. So what?
