It might be better to shift the "I understand" to after Mace has said he isn't a Master but still have Anakin give everyone a bit of dirty look (dropping the "What?").

Your take is better but it still shows Anakin's hand too openly.

^ This. Anakin being pissed off should just be implied. We should be eliminating all these whiny "throwing all his toys out of his pram" moments.

Also, I find it hilarious that in Lucasfilm, the left hand never seems to know what the right hand is doing. They seem to want to establish in this film (out of sheer convenience I'm guessing) that Anakin would be the first non-master ever assigned to the council in the history of the Jedi. Yet I remember reading specifically in previous books (notably the visual dictionaries) that Ki-Adi-Mundi was the only Jedi Knight currently on the council, and this was because he had not yet taken a Padawan. So not only have they fucked up continuity between a (factual- not eu) book and film within a 3 year period, but also they've changed the meaning of master from having trained an apprentice, to just being some shallow rank.

Irrelevant if you view these films as self contained, but it just shows that Lucas doesn't give a shit about continuity and will force any bullshit storyline or facts in order to get his contrived CGI laden events to happen.
