I think it was form without substance. There was the makings of a great story here, but it was ruined by the bullshit that Lucas crammed in. All of the good feels come down to the fight between Anikin and Kenobi, Yoda fleeing and the birth of the twins. This completely overlooks the massive problems with tone (showing comedy slapstick with R2 while Anikin is decapitating Dooku?) pacing (long and fast fight/chase sequences interrupted with stilted dialog on other locations) and character development (Anakin going back and forth in his transformation to Vader). The last 30 minutes could have been used to replace the entire prequel trilogy and done a better job at dong it.
