I prefer Shaw because I usually watch the saga in Release Order, so at the end of RotJ, you the viewer haven’t seen Hayden yet, and a first-time viewer would be confused about who he is.
Also, Shaw looks more like a proud father. Hayden looks…off. George really should have shot some proper footage of Hayden for that moment, if he was so intent on changing it.
Do you think it could be a good lead-in to the prequel movies if someone were to see Hayden on their first viewing of the OT and ROTJ?
