Let's not speak for the entire audience, mmkay? Even if I wanted to smack Anakin at times, I was still moved (particularly in Tatooine scenes and Immolation). I even get sad when I see little sunny Anakin in TPM, despite Jake Lloyd's occasional stiffness and "Yippee!" stuff. It's all about broken dreams and wasted potential... As for charisma, it comes from self-confidence and that's something Anakin lacks. Charisma is needed for antiheros (Han in ANH) or wise older mentors (Obi-Wan).
