Can't say I did... though I did notice that the N'avi had 4 fingers. And can I say how senseless it is that Na'vii has an apostrophe in it? What is that supposed to represent? Is their name actually Narble Vii and it's a contraction? They don't have a written language that we see, let alone one in latin characters, therefore the written N'avi is a human (english) representation of their name, which obviously should be a phonetic rendering of what their word SOUNDS like. And nothing SOUNDS like an apostrophe. Lame. QED.
