Finally, someone's addressing the glaring flaws of this film. I'll continue.
4) Poor use of characters. C-3PO helped to translate Artoo's beeps and provide exposition in A New Hope. All he does here is annoy other characters and get blasted by Imperials; just so he can be the wacky comedy relief. Way to ruin the dark tone of the film Lucas!
5) Sudden character betrayal. Lando's betrayal of the characters has absolutely no impact because he's been introduced in the film and we hardly know him. Now if beloved character "bearded Rebel guy who talked about the Death Star" had done it, then the audience would have had some real impact.
6) No continuity. Why isn't Luke talking about Beru and Owen? They were his adoptive parents and not once does he mention them. Guess they just didn't matter. And why didn't we have a scene of Han reminiscing about shooting Greedo? That was a good scene and its never brought up again even when Han's dealing with another bounty hunter and talks about Jabba. What a waste.
7) Powers as the plot demands. So Ben can appear as apparition as well as speak to Luke. Well I'm glad that was explained. Oh wait, it wasn't.
8) Offscreen shenanigans. Han had lots of money that he could have payed off to Jabba, yet there's no indication of why he didn't or what happened with it. Evidently Han ran into a bounty bounter on Ord Mantell which had a big impact on him. Yet we don't see any of it, not even a flashback. So I guess there was some other movie story that Lucas didn't feel was necessary for the audience to see. Real nice.
9) Discriminatory character treatment All the major figures get character development. All the human characters. Artoo, 3PO,and Chewie get nothing more than supporting roles and don't seem different at the end of the movie. This is the way Lucas treats beloved icons of popular culture.
10) Inconsistent character points Lightsaber is the weapon of the Jedi Knight; Yoda never teaches Luke with it. Vader's appeared loyal to the Emperor in the past; is now offering to overthrow him. Luke reveres Ben's lessons about the Jedi including their weapons; still uses a blaster which was called a clumsy weapon. Was this movie made with the first draft of the script or something?
Hmph, what an absurd movie.
