It probably would have been if Spielberg had gotten to direct it, as was Lucas' first choice. I blame those vultures at the Director's Guild at the time for trying to pull Empire from the theater and fining Lucas -- and even Kirshner -- for simply having all of the screen credits at the end of the movie.

I always heard David Lynch was supposed to direct JEDI (it was when he either left or was replaced that he went on to work on DUNE). Regardless, did the DG really try to pull EMPIRE for having the credits at the end, being that it was no different than STAR WARS: ANH did when Lucas had far less clout?
