They should make another one that is a horror movie and serious, Get Caulkin to play a grownup and wacked out people are breaking into his house. Everybody would tune in and watch out of curiosity.
Twenty five years after his adventure in New York, Kevin McAllister is a recluse.
Mr. Duncan, upon his death fifteen years ago, bequeathed the Toy Chest business to the little boy who helped him back in '92. Kevin thought that helping children live their dreams would satisfy the hunger inside of him, but his paranoia simply grew and grew until he could no longer function. He has sold the Toy Chest to FAO Schwartz and, using the money from the sale, has bought a huge compound in Winnetka.
Kevin's mother and father come to him during Advent to bring Kevin home for Christmas. Over the years, they've tried to get Kevin the mental help he needed. Kevin had been making progress, but the death of Old Man Marley and the Pigeon Lady drove him deeper into his madness.
Upon reaching the steps to his house, which were iced over to prevent intruders, Mr. McAllister falls and breaks his hip, leading to massive medical bills and what will be a Christmas in a hospital bed.
The Winnetka police, upon learning of this incident, send two cops over to Kevin's house to investigate, when they too fall victim to a trap. Seriously injured, they retreat to their cars and back to the station. The police union gets involved and refuses to have any more police officers go to Kevin's house, for fear that the master of traps will cause more physical harm.
At a loss for how to deal with Kevin, they decide that there are only two people who can bring Kevin in. The two individuals who suffered through Kevin's worst traps and survived. Two criminals who were returned to Illinois after their fisaco in New York and are serving long sentences. The criminals with nothing to lose: The Wet/Sticky Bandits.
The mayor of Winnetka calls in a favor to the governor of Illinois. An offer is made: full pardons for the Bandits if they can bring Kevin in. They agree, but only if they can do it on the one night of the year they most want revenge, the night where they have always been foiled: Christmas Eve.
HOME ALONE: THE LAST CHRISTMAS. CHRISTMAS 2017.
(Title could use some work. Maybe throw something in there about the Bandits enlisting the help of Kevin's illegitimate daughter, who is some sort of Rub Goldberg genius and could help them make it through the house alive. Plus I'm almost 100% sure someone else has come up with this idea and probably pitched it to Fox. I mean, it pretty much writes itself.)
