John Carpenter’s They Live! — An Escapological B-Movie if ever there was one.
From what I remember, it’s a bit pointlessly violent (~ten minutes of splattery ’80s machine gun nonsense) but look at those cool dystopian billboards. CONSUME! OBEY! WATCH TV! GET YOUR HAIR DID!
Apparently, there’s no exclamation mark in the title, but I think it deserves one.
