So I'm imagining a reboot, where adult Macauley Culkin is accidentally left at home by his wife and kids and figures out some robbers are coming. Rather than calling the police like a normal adult, he lays elaborate traps, many involving his current "toys" (power tools). It plays out the next 20 minutes as a Saw-like vignette, then the rest of the movie is a courtroom drama where he is being tried for the murder of the robbers. Does Castle Doctrine cover him? Can he consider it self defense if he never called police even with enough time to set up traps? Will he get treatment for his mental illness as his wife has been begging him to do (plot twist, she didn't forget him, she left him at home and took the kids to her family's for safety)?

Also the robbers are still Harry and Marv (just got out of prison) and they were old as shit and very much not a threat as robbers to a grown ass man.
