" Why not? You ask the same question of the Separatists." how difficult can it be? once again I will explain: In TTT you have a climactic battle. What do we know about the two opposing parties? We have our heroes that we know very well, we know their strategy, they show emotion, wit and desperation. Then we have the Uruks. We don't know every Uruk. We don't need to know every Uruk. But we know what their purpose is, their goal, their ability, their strategy. We know enough about them to hate them. Result: We CARE. In AOTC you also have a climactic battle. What do we know about the two opposing parties? We have the Seperatists. We know nothing about them. We don't know where they come from, what their goals are, whether their cause is just or evil. Their strategy, as far as one can make out, is "let's shoot at everything that moves". Then we have the Clones. We know nothing about them apart from the person they were all created from. They have no wit, no intelligence, no emotions, their strategy is "let's shoot at everything that moves". On top of that the outcome of the battle doesn't matter. Result: Nobody cares.
