If you want a movie that illustrates the downsides to anarchism then watch this. The problem is it's not set in an anarchist society so the entire plot doesn't make any sense. (MINOR SPOILERS FOLLOW) In addition to a plot that doesn't make sense it has wildly unrealistic parts like adding a bunch of silly super powers to bigfoot. Like most kid movies it will leave you warm and fuzzy given the events at the end, but overall it's not a great movie.
