The OT is not that great story wise either. Guess what propelled Star Wars back then? Visuals and atmosphere. It was new back then, seeing stuff like that. EPV was somewhat not that cheesy, but still nothing extraordinary. The flow of the story, the Empire's status and power relations are all messed up, pretty much to serve great action scenes. Ad-hoc stuff thrown together to look cool, which was a success. SW was always about the action, visuals AND coolness, which the ewoks and jar jar go against. Why do you think Boba Fett is popular? Because he is cool. People have to look behind the mist of nostalgia and memories. SW was a memorable flick, a first of its kind, just as cheesy and about visuals as the movies people like to criticise. I am not saying I don't like SW, but I don't go there for the story. It has to make sense on a level, but great stories are for more serious movies where there is time to develop them.
