Just some guy filming kids in the park..ok okay, not creepy at all
Plot fail.
I don't care if those were his kids, objectively that is such a creepy and silly way to set up that heartfelt moment.
Why not get out the car, play with your son at the park, and watch tearfully as he finds his sister and plays? Why just stay in the car and film like some pedophile? Like what did him staying in the car add? Nothing. To his son he seemed aloof, and he was absent to his daughter. He knew these things, and decided to play a little woo woo "you've known each other all along" joke on them from beyond the grave. WHAT? Why not get out that car and be an active parent? I don't get it. It's so stupid. Whoever thought of that has no imagination or critical thinking skills.
Imagine if in the film some colleague or fan of his character saw that tape somehow (not his wife, because she knows what Sam looked like as a child), it would literally look like he was on his creeper status, filming kids in the park.
Just bad. Just awful. It was cute in the moment at the very end when they were watching, but I was just thinking "wait a minute....some guy was just filming kids in the park and no one thought that was weird? No one?"
That part should have been scrapped. Movie should have ended with them on the porch being brotherly and sisterly.
