"MOM!" Ironically, this is probably Marty's most disturbing film. Remember that uncomfortable scene in "Taxi Driver" where Bickle flies into an embarrassing tirade at the campaign office? Stretch that out over an entire film, and you've got "The King of Comedy," for better and for worse. Jet-black humor offers some levity, but this is a painful, cringe-inducing study of celebrity worship and loneliness.
