This film is a Progressive Socialist's Wet Dream
Because the aliens totally CONTROL people just like the Progressives want to because they think they're smarter than us and know better how to run our lives. They're Fascists because they want to run over the Individual and his/her freedom for the good of the masses. They want a Socialist/Fascist Utopia.
Other than that problem I did like the film because I like British humor.
