Part of the problem with AOTC is that it has two desert planets (one orange and one red) in the same movie. It would have made for a better narrative if both of those worlds were Tatooine (the droid armies explaining how the Jawas get to sell so many salvaged droids and why the locals don't like drinking with them). in terms of numbers you get two worlds but in terms of the richness of the environments in which the story is told we get short changed.

For this to work, Obi-Wan (and Qui-Gon if he keeps the role that he has in TPM) would have to discover Anakin after being drawn to Tatooine by the war. The army being constructed on the same planet that Anakin was discovered on 9 years earlier is too much of a coincidence.
