partway through you find out that the three families are actually all in the same house in three different time periods. And connections between the families through the years are slowly revealed over the course of the movie. And then the next three movies each revisit one of the original families, but add two other families from different time periods. So by the end, you have a whole history of the house from the 1950s to the present day and it's really cool. Cheesy af ofc, but neat
