This is strange. Normally in these forums I'd likely question Voyagers logic of continuity but now in the Star Wars Episode II "high" I'll comment on my first sci-fi fascination. Overall despite the "hokey" bits AOTC is an okay movie and much improved over "The Phantom Menace".
The problem I find though with Lucas' obsession with tying everything in for the classic trilogy is where certain details will contradict themselves later. Unless he explains some things in the final Episode III prequel certain details the audience are aware of now won't make a lot of sense when we watch the films sequentially;
1. C-3PO is built by Anakin Skywalker, Luke's father and goes with Shmi to work on Lars moisture farm. By Episode IV: A New Hope C-3PO quite obviously has no idea about Tatooine, his "maker" the former Skywalker, that he worked with Owen Lars, or moisture vaporators that well and much less about his maker's Jedi Master Obi Wan Kenobi when R2-D2 sets off looking for him.
2. In Episode IV Owen Lars buys C-3PO and even his sidekick R2-D2 but seems to have a memory gap
about the both of them being on his farm when Shmi is buried and R2D2 delivers a message from Obi-Wan Kenobi in Episode II. If R2-D2 is understandbly unrecognizable C-3PO should not have been. Lars must have seen many "C-3PO"s come by via the Jawas.
3. R2-D2 has no memory of Anakin Skywalker in Episode IV either. R2-D2 does claim to be owned by Obi-Wan Kenobi. In AOTC R2-D2 is equipped with repulsorlift rockets which are never used in the classic trilogy. When R2-D2 jumped Jabbas barge in ROTJ they would have come in handy. The thing is despite the problems with the droids if Lucas makes mention their memories are to be erased it would explain the obvious questions that arise otherwise. Also other owners/masters of the droids could have uninstalled parts like R2's jets from Episode II. As to whether Obi-Wan will plant a mind trick on Owen to forget about C-3PO who knows we'll see.
4. Obi-Wan claims that he never owned a droid nor recognizes R2-D2. In Episode II he has a starfighter and an astromech droid and knows R2. Will Yoda mind trick Obi-Wan in Episode III? Obi Wan also has that "truth from a certain point of view" twist about Luke's father (although it is hinted at when Obi-Wan looks at both Luke and Vader when he forfeits to his former pedawan on the Death Star) but Kenobi also mentions that Luke's dad was not only a Jedi but "the best starfighter pilot in the galaxy" so far Anakin piloted a "starfighter" once, only by sheer luck too, on one mission when he was a 10 year old destroying a Trade Federation battleship. Seems like folklore or galactic history is not taught much in the Empire era or certainly not on Tatooine or else Luke wouldn't have to ask about his flukely dad from a "crazy desert hermit". Also Obi-Wan was the pedawan of Qui-Gon Jinn not Yoda as was hinted in the dialogue of Empire Strikes Back...."the Jedi Master who instructed me" but thats a minor nitpick.
5. Vader does not recognize C-3PO or his familiar rantings on Chewies back in the carbon freeze chamber in ESB. Nor that Leia Organa might be force sensitive in the Death Star's detention block interrogation and may resemble his old wife Padme to ask her who her real mother is. He'd certainly clue in as to the possibilty he was daddy. Maybe Admiral Motti was right about Vader not having "clairvoyance enough".
6. Some speculation is Padme Amidala dies in Episode III. That would contradict Leia's memory to Luke in ROTJ. Luke asks if she knew their mother, their real mother which Leia replies that she remembered she was very beautiful but always very sad so it seems likely Padme goes with Leia to Alderaan with Senator Bail Organa. It seems the explaination in ROTJ is Luke gets seperated from his biological mother to protect his discovery from the "dark side" of the force. Obi-Wan chooses Anakins step-bother to care for Luke on Tatooine and lives there himself.
I certainly wouldn't want to be Lucas. He's gonna need the Force alright.
