I still don't understand how introducing Anakin at such an early age did any service to the overall story, they should have gone with a mid-teen that was closer to Natalie Portman in age. The problem is you can't expect an audience to make an emotional attachment to a character they know will grow up to become DARTH VADER

By introducing Anakin so young they wasted a whole movie where they should have been establishing the friendship between Obi-Wan and Anakin, and the beginnings of a budding romance with Padme, and as a result none of their characters showed any character development until the 2nd film
