AAAAAAHHHH!!!!!

Actually, my immediate thought upon first seeing that horrible scene in AotC was, "If R2 had rocket boosters, why the hell didn't he just use them to escape falling in the swamp in ESB?!"

And then later, "Why does he have to be hoisted up into the back of an X-wing if he can just fly up there?!"

Not only did the AotC scene itself suck the dog balls, but from a retconning standpoint it's a complete disaster. I think there are only two reasons why this change hasn't been put into the SE's: one, the whole live action sequence would have to be basically scrapped; and two, it probably never occurred to them that there was a continuity problem in the first place.

Otherwise, I shudder to think what could have happened . . .
