There was a thread entitled "Visual Storytelling at its Greatest: In Depth Analysis" in which posters were giving Lucas all kinds of credit for basically using the same shots from movie to movie. True, there was some value in some of the parallel shots, but the thread was filled with inappropriately high praise.
Lucas loves to reuse ideas. There's Boba Fett in Ep. II, Chewbacca in Ep. III, Jabba and Greedo in Ep. I (yeah, it was a cutscene, but Jesus! Greedo?!?) - and that's just the short list. And in TPM, Lucas had the chance to introduce another parallel - the journey of the father echoing the journey of the son, but he started Anakin at the age of 10.
The PT fascinates me. It could have been much more, so very much more, than it was.
