I also must admit that I kinda liked Attack of the Clones. It seemed to head the prequels in a more StarWarsian direction than Episode I, and I actually found it enjoyable the seven or eight times I saw it in theaters. That I can't bear to sit through it now does not take away from the fact that I enjoyed it when it was released, something I cannot say about either of the other two prequel films.
But I'm glad I saw all of them. Even Revenge of the Sith, which I deplored with all my being.
