We wuz promised Wookiees, dammit. Back in the 70s, even the 'official' rumours mill -- the fanclub newsletter -- told that there would a be a return to Chewbacca's homeworld in the final film. Mind you, it also said the title would be _Revenge of the Jedi_, and that turned out just to be a smoke screen to fox would-be bootleg merchandisers.
No, we got a bunch of creepy-eyed teddies bumping into each other and squealing "Eecha wamba!" and such like, all to cash in on kids' gullibility.
Oh, and Boba Fett turned out to be rubbish as well.
20 years on and I'm still bitter about it. You can tell, can't you?
