Do you see my point? There has to be a standard to everything, some sort of rule we can judge and compare things to. I didn't like Citizen Kane...however, it has an excellent story, excellent filmatography (sp), and really great acting.
As for the Prequels...so you didn't like them, that's great. So you did like them, that's great. But are they really that great movies? No, they are flawed compared to others. Whether you enjoy them or not is up to you.
Just try not to get sucked into the realm of thought that says that if you like it, it's good for you. That's just ridiculous.
