Anakins theme was to foreshadow what he would become. But it was for us. It was a reminder to us that this bouncy little kid would become Vader. If this was obvious from the images then there would probably be a different Anakin theme in TPM. But it wasn't obvious except to the people who know the story.
Someone who had no idea what SW was about and had never seen the OT would watch TPM and only the tone of the music would hint at Anakin becoming bad.
No, but he is mostly NORMAL! That;s the whole point, people keep trying to find his 'hidden Dark Side' in all these things where as actually thar's just the same as anyone out there, no hideen reservoir of pure evil. And in many other ways Anakin is quite the opposite.
The Jedi did not voice concern over his anger or aggression. It was his FEAR, a problem so deep-seated that only the Council could uncover it, it was not obvious on the surface.
