Personally, I find it more compelling to see Anakin redeemed and becoming the person he should have been, which in ROTJ is Shaw, rather than an apparent regression to before he made the final few steps to turning evil.
That’s an interesting perspective.
Also, until somebody like jhon, Sir Ridley, or Snooker does a “good” version of the Hayden Anakin ghost (i.e. not using Shaw’s body, Anakin giving a truly proud or happy expression like Shaw, and maybe wearing something akin to his ROTS robes), I’d say stick with Shaw.
I totally get your preference, but it’s more than just “purists” who prefer Shaw.
I do think that it would be great to see that, as it does kinda bother me how in one of the shots he kind of gives this creepy-vibe with one of his smiles. But until that happens (or I should probably say if it does) I’ll probably still stick with Hayden.
I do apologize for that rather ignorant, gatekeeping statement.
