The story that you say goes nowhere resolves the conflict between Luke and Vader, restores freedom to the galaxy and all but guarantees that Han and Leia will live happily ever after. All that, and Anakin Skywalker is redeemed and dies as a Jedi Knight, reconciled to the good side of the Force and to Yoda and Obi-Wan.

I prefer ANH and ESB over ROTJ myself but how can you argue the story of ROTJ goes nowhere when it covers all that ground?

I would agree that the Leia-As-Sister sub-plot goes 'nowhere'.
