Obi-wan Kenobi, Lando Calrissean, Darth Vader, Chewbacca, Anakin/Luke Skywalker, Han Solo, Yoda, Jabba the Hutt, Aayla Secura, Qui-Gon Jinn (even though the character was redundant), Darth Sidious, Princess Leia Organa, Wedge, Dak, Bib Fortuna, Salacious Crumb, Artoo Detoo, See Threepio, Greedo, Sebulba (albeit another useless character in a useless podrace), Admiral Ackbar, Darth Tyrannus (if only they SAID the name!).
Some dud names:
Nute Gunray, Jar Jar Binks, Count Dooku (perhaps if it was Count Doku, it might've sounded cool and Japanese - but then, why the hell are there Counts in the SW universe?), Boss Nass (here's an idea: ditch the Gungans!), Watto, Darth Maul (but I must say, it's difficult to come up with alternatives), Shmi Skywalker (I probably hate this name the most, reminds me of Captain Hook's right-hand man!), General Grievous, Commander Cody (probably third worst), Jango Fett (fourth worst, sounds like the name of a fruit bat), Elan Sleazebaggano (oh, I get it! He's a sleazebag!), Panaka.
Why do all the characters have to be named anyway? Why couldn't Elan Sleazebaggano simply be called 'Deathstick Dealer' or even better, be cut from the movie?! I have to defend the name of Padmé. Even though it sounds stupid coming from the characters' mouths, it comes from the Buddhist adage The jewel is in the lotus; the lotus being 'padmé' in its original language. So I kind of liked that there were still some Joseph Campbell references in the PT, even though GL seemed to still miss the point...
