Why many people likes older star Wars than newer ones?

the reason I didn't like the the new ones, the prequels, is that Lucas used CG effects as a crutch and was in love with it. Where as the Original trilogy he used special effects to aid the story not be the center. He let his political view seep into the some of the Dialogue and banter in ep III, I am not saying I disagree but it did ruin the story. Another problem is the concept of Anikin, in Ep I, understanding advance robotics and AI and it is treated as a normal occurrence, now maybe its my ego being bruised but it seemed to far fetched, In ep II, Obi Wan is oblivious to the plot holes, the plot hole are so evident not just to the viewer but if the character was real and he put his overall experiences together he would know the truth, which comes to my biggest problem, its not realism, graphics, but the fact that jedi, yoda and co. accept things without question or inquire. Ok bounty hunter connected to clones, clones secretly made, accepting them without investigation, jengo connected to dooku. Hmmm. If you watch ep II and connect the dots you can see the connection and with only the same knowledge the characters have.
