I'm in the camp that Shaw's ghost is as (if not more [but that's a different argument]) ridiculous than Hayden's. Anakin just shouldn't have a ghost, period. Another place where ROTJ dropped the ball in favor of picturesque, happy-feeling, "we're all done now," high-five, "we all did it guys!" everyone's okay (even the guy who sacrificed himself because this whole thing was his fault) ending.
