Most of the places in the original trilogy weren't iconic -- a majority of them were either indoor (Cantina, Bespin, Death Star, etc) or inside a space ship (Falcon, Star Destroyer, etc). When you saw a world it was either not very interesting (a desert, a forest) or a matte painting or CGI. What was iconic was the characters. But for whatever reason the sequel characters never caught on. People compare the land with a Potter-ish but Potter also featured iconic and unique locations that could be reproduced (Hogwarts, Diagon Alley) as well as the characters.
