It has improved visually, that's it. Of course the prequels have not improved the series, they're simply not as good as the original trilogy. But to me that's not really the point, I realized about 6 years ago that they weren't going to improve upon anything.
Theres some stuff I hate in the new trilogy (Jar-Jar, some of Hayden Christensen's performance, even some of the otherwise talented Natalie Portman), but there's still plenty that I enjoy (Palpatine/Sidious and his manipulation of the Republic, Obi-Wan is pretty cool, all the droid and clone armies and battles), and of course I'm looking most forward to Episode III since it's the birth of Darth Vader.
One thing I have to say is that I DON'T think Episode III will be very dark... not nearly as dark as everyone is hoping for, despite Lucas himself saying that it would be. To Lucas, Ewoks fighting is 'dark'. He doesn't understand the term. The Star Wars prequels are kind of like the Spiderman movies, too colorful and bright to ever be a dark film.
In fact, one of the most telling quotes I ever saw from Lucas, showed me that he really HAS NO IDEA how the modern movie world works! It was actually quite disturbing to see how out of touch he is. Basically he said that he thought Episode I would make the most money, then Episode II would make only
half as much, and finally Episode III would make
half THAT much. His reasoning was that each film was going to be darker, and so would
earn less money because
less people would enjoy it. Poor man! He doesn't even realize that we WANT dark! DARK DARK DARK, please! That's what we want! And he thinks the exact opposite, he thinks he's making it dark because it has to be, but that the fans will hate it.
