Ben (ROTJ): When I first knew him, your father was already a great pilot, but I was amazed at how strongly the Force was with him. I took it upon myself to train him as a Jedi. I thought that I could instruct him just as well as Yoda. I was wrong.
Read that line while you have images of TPM in your head. Does that really seem to match up with this?
Obi-Wan (TPM): The boy is dangerous. The council senses it. Why can't you?

New Emperor scene: Well, I just want to ask you why you think it's better to watch them in numerical order. Since the prequels exist solely to explain the events in the original trilogy, doesn't that ruin the emotional impact? Also, the prequels contain so many "cool" in-jokes to the original trilogy that you simply wouldn't get if you didn't watch the originals first.
The big contradiction. How in the world does Leia remember her mother if her mother died three seconds after she was born? The way ROTJ Leia talks about her, it sounds like they were together for at least a few years before she died. It simply does not make sense that Leia would remember her and Luke not if they were both newborn infants. Explain that one, please.
