Well the ring theory does explain the film structures, it doesn't explain though the poor film making. In Ep I the main character, Anakin, isn't even introduced until 30 minutes into the film. Padme's identity as the Queen is kept a secret from the audience - so she isn't even introduced until 30 minutes in either. Qui-Gon, a trained Jedi Knight, rushes in to fight Maul without waiting for Obi-Wan. Portman was quite flat at times, for instance in Padme's plea to the Gungans - there's no emotion or sincerity in her voice. In her speech in fact her voice changes tone for no apparent reason whatsoever - something that would have been easily fixed back at the studio during re-dubbing.
