That's a good beginning Darth, and if we had never seen Tatooine or the homestead or the binary sunset before, I would have no problem with it at all. Problem is, we see Tatooine twice in the OT, and three times in the Lucas Prequels. That's an awful lot of time to be spent on a planet where even Luke says there's nothing to see.

I think that if we are going to focus on Anakin as the protagonist of these movies, it should be after he becomes a Jedi, and even after he has been trained by Obi-wan. The reason is that the OT can be viewed as an exploration of Anakin's past. We begin on the planet of Anakin's birth, meet his brother, then meet the man who trained him, then travel to Alderaan like Obi-wan (and perhaps Anakin) did in the Clone Wars, and have Luke be trained as a Jedi, except that this time he is trained by Yoda, not Obi-wan, and this makes the difference in him not turning to the Dark Side. To repeat these beats in the prequels seems unnecessary. Of course, the only story left to tell at that point is how Anakin the Jedi became Darth Vader, and we don't really want to spoil the surprise, so we've brainstormed ourselves into a corner.

Alternately, as has been suggested, it could be about Obi-wan, and how he was a hotheaded Jedi who eventually cooled down and became the serene mentor we know in the OT. The trilogy could begin with the outbreak of the First Clone War, and could even end at the end of the First Clone War, when he is rescued by Anakin who is piloting a spice freighter and happens to be in the area. He is tired of war by this point, and Yoda has told him to pass on what he has learned, so he promises to train Anakin to take his place in the Jedi Order, and he is able to retire from war in peace.

OR DOES HE???? ;)
