I have to say that I agree in essence with everything Bingowings just wrote, yet still personally enjoy ROTJ. Not as much as the other two, but I still enjoy it. What I like is: the score (not my favorite, but still strong), the sets/models/environments, strong performances from... some of the cast, and it closes the story started by the other films in a somewhat satisfying way. But yeah, the script is thin, the Lucas-cutesy-humor is off-putting, and certain cast members just phoned in their performances. But it is still undeniably a Star Wars film, something that I can't really honestly say about the prequels.
