I agree that the PT has names as cool and silly as the OT. Mace Windu is just an awesome name, and i rather like Count Dooku, Anakin Skywalker and even stuff like Captain Tarpals. I think the notion that the OT only had "normal" or "cool" names is bullshit: Boba Fett is lame ("boba"?? we accept it as "cool" because the character is cool), and then there is stuff like Sny Snootles, Obi Wan, and Grand Moff Tarkin. Personally, i don't mind any of them. They are supposed to be alien and exotic but also connotative of certain qualities: Greedo is greedy, Han Solo is a loner, Luke Skywalker has his head in the clouds, Leia Organa represents the human rebels in opposition to the artifical Empire, Darth Vader is the dark invader, opposing Obi Wan the "holy one."

The difference between the PT and OT lies solely in the fact that Star Wars utilised ordinary, contemporary names as well. ESB and ROTJ used alien or exotic names exclusively, even in in humans (ie Lando Calrissean), and ROTJ is littered with creatures with correspondingly weird names. However, the core characters from Star Wars remained with their American names, offsetting this. Honestly, thats all there is. Sio Bibble and Boss Nass are completely comparable to Nien Numb and Yoda. The difference is that the main characters are named Luke, Han, Leia and Ben, names that were common--at least in the 1970's--and in fact i know many people today that have these names, and this gave the films a kind of grounded reality and subtle familiarity.
