I like the point Matt made on Empire. I have always found it extremely ironic that Empire is the best one, and it has made the least amount of money. How can that be explained? Wild! I'm guessing that it's a generational thing. Most of us who say Empire was the best were probably between 6 aand 10 when it came out, and we didn't have the bank to see it as much as we would have liked (however, that didn't stop us from begging our parents everyday!! ). As we got older and started making money, it was easier to see Menace, because that was more within our immediate control.
Actually, I think Matt's assesment has more to do with quality. Because ESB was a quality film, it made the least money. Not to insult anyone, but the fact is is that people don't always like intellectualy films. They usually go to a movie to have a good time, not to get emotionaly bumbed out or have to think about what's going on. ANH was fun through and through, it was the ultimate crowd pleaser. ESB was a differnt experience, a darker one, that's why it didn't perform as well financially.
