Everyone I talk to about the movie is always like “Why didn’t the parents do this or that” but if you haven’t seen the film in a while, they do tie up a lot of loose ends:
- The phone lines go out so the parents can’t call Kevin directly.
- All the neighbors leave for the holidays so there aren’t any neighbors to call.
- Obviously, the parents call the police, but the cops are parodied as incompetent donut munchers who aren’t helpful.
- One wonders why they didn’t call the elderly neighbor that the kids think murdered his entire family. I realize a person rumored to have murdered his entire family probably wouldn’t be your first choice to help your kid but one would think the McAllister parents would have been wiser than the kids and would have known that the old man is just a grumpy old man and not a murderer.
- So if your local police department won’t help, wouldn’t the parents have called the state police, the FBI, or just keep calling law enforcement agencies until someone locates Kevin?
- Is there no adult in the area they could have called?
- What about the mayor’s office or the governor’s office or something?
- Does Kevin go to school? What about like calling the school and see if they’d talk to the police to do more?

They can’t call the police, the parents would have been arrested for felony child endangerment. Just look at the news. It happens all the time to parents who let their kids go to the park. Can you imagine going on vacation without your child….
Eh…it was 1990 though. And you might take the charge to keep your kid safe. I’d forgotten a lot of the loose ends they go through but they do call the cops and there’s one cop eating a donut and another knitting a sweater and they keep transferring the mom back and forth

To make it even worse, they left him alone in New York City in the sequel and he had to ask Donald Trump for help. No child should have to suffer through that.
One would think that the parents would handcuff themselves to Kevin while going on vacation ever since the first film
