are you saying it didn't have good action scenes or that it messed with the old characters? or both?
SPOILERS
The medal ceremony after the destruction of the first Death Star has just come to an end. Luke is hanging out at a Rebel after-party, and he spots Leia.
Luke: Hey Leia. Now that we have some time to breathe, I wanted to ask you something. Just how did you get roped into this whole mess anyway?
Leia: Well...it's kind of a long story.
Luke: I'm all ears.
Leia: Well, my father, rest his soul, was one of the founding members of the Rebellion. Actually, R2-D2 and C-3PO were there too, which is why they were on our ship, the blockade runner. Before that, though, we were all here on Yavin 4. You see, earlier Mon Mothma had hired this girl Jyn Erso to go find this guy Saw Gerrera, but lots of stuff happened and when she came back she told the council about the Death Star. Oh, it turned out her Dad had worked on the Death Star himself and it was he that designed the flaw.
Luke: You mean the exhaust port that I had to use the force just to shoot some proton torpedoes into?
Leia: That one.
Luke: Not much of a flaw, is it? I mean once I made the shot Han was all like "Great shot kid, that was one in a million." Did he expect the Alliance to have a pilot strong in the force in their ranks?
Leia: Well, Galen Erso was a guy who liked taking chances. His password to the Death Star plans was "Stardust", so I guess he was banking on his daughter being the one to personally be on the planet which was storing the plans, and also to be the one to personally be the ones taking the plans.
Luke: Huh.
well, to be fair, he had to make a flaw in the death star that still would've gotten unnoticed by the empira ---
