I respect you and your opinion, but if you have to assume that much stuff happened off screen it’s a them problem. I’m sticking with my original assessment.
Also, in a movie where someone wakes up from a coma and somehow finds the doctors to perform the surgery on him (including the voice changer thing which would need a recording of Travolta’s voice) to put someone else’s face and body on his and then murders them without anyone being the wiser, the “it’s cool that this kid lives here right?” Part is still the most unbelievable to me.
In a movie where criminals are sent to a secret magnetic shoe prison on a oil rig in the middle of the ocean and a man jumps off the top of said oil rig and falls like 200 ft and doesn’t just die on impact, the kid thing is still less believable to me.
Also, my family do weird things that are in jokes and stuff, but hand thing just like, it’s too weird to just be in the movie. If there was a scene where they were like “we do this hand thing to show we love each other because GamGam use to do that during the war” or something then sure. But the fact that it goes unexplained is the real problem.
