To me it looked like a lot more action and a lot more revelation of plot that we've been hearing about since the first trilogy.
A lot more is revealed and tied into the original trilogy than The Phantom Menace (which more or less could stand alone).
[UPDATE]
I removed what I had said because I don't want to spoil anything for anyone that happens to read it. It was vague, but it did give away some of the story (from what I have read online).
I did put a post in the
suggestion box, asking for a spoiler tag if we can get one.
