Interesting. I was under the impression that Lando was flirtatious with the girl (with all the pairings alluded to just before or after...) I probably got the tone wrong.
Overall, I liked it more than the first prequel and the two sequels. I'd rate it below AotC and RotS. Pacing was a little off at first, I concur with what other have been saying. We do get a lot of "deus ex machina" moments, especially for the appearance of the "fleet" at the end when they already tried to pull this off at the end of the previous film and failed to gather a large support. Explanation of why it worked this time, when they got no significant victory to gather support around them was a little bit lacking ("it's them making us thinking we're isolated..." wuh?)
Some scenes were cool or fun (the spy one, the arrival the feast of the ancestor...) and the overall aesthetics on par with the other sequels, which is a good thing imho.
I don't think we'll see more of the Emperor. I understood him to be more undead (saying that the Dark Side allowed him to do unnatural things) rather than cloned. If cloning in SW terms is even remotely related to what we call cloning, his clone, even old, would look like Palpatine, not the wreck of a man he was made after the fight with windu and overusing his dark sides power to off him.
