Regarding the argument that the “Shaw ghost never existed”, well…the Hayden ghost never existed in that specific form either. He clearly has both arms intact when one should be missing (and yes, both hands are visible in the wide shot). So if the Hayden ghost is okay from that standpoint, then so is the Shaw ghost. Therefore, the “Shaw ghost never existed” argument is no longer valid.
I’m not saying the Hayden ghost is perfect. It’s just the less wrong option.
