That, and killing off the best bad guy in the first movie didn't help.
Darth Maul was pure Boba Fett: Some guy who looks cool and says nothing, a perfect toy but a little light on the ground as far as villains went. I think he actually had more dialogue in his teaser then he did in the actual film:
He looks cool and he kicks ass. What more do you need (particularly when you have Palpatine to do all the dialogue-based villainy)?
I have to admit I kinda agree with the fans who say that they like the prequels better than the original trilogy. Granted, no one in the prequels manages the same kind of effortless screen chemistry that Luke, Han, & Leia have. But there's more pathos in the last half of Revenge of the Sith than there is in the entire original trilogy. And while dialogue & nuance were never Lucas' strong suits, the prequels are a masterpiece of visual art direction. Using limitless technology & a near limitless budget, he created an exotic alien tableau of epic proportions that I don't think any other filmmaker will ever have the audacity to try to match. I admire Lucas immensely for making the prequels his own. Watching the bonus features of him at work, he's clearly just a big kid playing make-believe with multi-million dollar resources.
There's a school of thought out there that production values don't matter so long as you've got a good story. (Being an old school Doctor Who fan, I'm very familiar with this mindset.) But couldn't the opposite also be true? If Shakespeare's words need no visual embellishment, then why is dialogue embellishment so essential when the visual pallette is so rich?
My heretical ranking of the films:
- Revenge of the Sith
- Attack of the Clones
- A New Hope
- Return of the Jedi
- The Empire Strikes Back
- The Phantom Menace
