I don't really have a problem showing Tatooine because if one does something interesting with it and it demonstrates something about Anakin's character than it can be worth it. Tatooine in my current draft is not quite the complete dump it is come ANH. Its a planet with potential as there's a growing economic interest, a time before a devastating war and 20+ years of Imperial neglect will ensure it never becomes more than the barren rock Luke Skywalker is so accustomed to.
It ties into why Luke and Anakin having similar origins can work if one his able to highlight the contrasts. In my version, the latter is not really a bored farm kid longing for adventure like his son will be. He's part of a farm that's doing relatively well, a stable spice freighter job that gives him occasional flying time, and enjoyable friendship with his coworker Carima. His dissatisfaction comes from a feeling that he should be doing more for other people, a sense of duty in doing some kind of public service for those who need help.
Anakin is, in a sense, the middle class kid who gave up a decent life to sign up for the peace corp (or alternatively joined the armed services) because he wanted to make a difference. He made the sacrifice of a stable and peaceful existence to indeed follow Obi-Wan on that damn fool idealistic crusade because he was an idealist, a fact that allows him to fall so hard, so badly because his hopes were so high.
