Yes and Sheldon is right. Lucas worries more about Special Effects than the actual story. Plus he's a terrible director. Several actors (Liam Neeson, Ewan McGregor) almost quit because he is so bad. But luckily the many authors of the E.U. (Expanded Universe) have created a very rich universe and has nothing to do with him. You can tell that by the inaccuracies in his movies. For example: If Episode 3 and Episode 4 are 19 years apart, why did Obi-Wan age 40 years!?! And killing off Darth Maul in Episode 1 was worse than Greedo not shooting first.
