I feel what George did with Jar Jar Binks, the underwater submarine ride, and the Gungans in Menace caused a ripple effect through out the Prequels, so as we know now Anakin and Obi Wan werent close friends and Anakin hasnt interacted properly with Palpatine until Ep 2(two essential relationships for the trilogy and weakend it by not showing proper relationships with both throughout the three movies)
