Movies for which a sequel is totally inappropriate

Whenever I imagine a sequel that should not be made, I always imagine the title will be “[movie title]: [greater amount of movie title]” or “[movie title] 2: Electric Boogaloo.” Try it with any of the movies on this list:

• Fair Game: the Valerie Plame story
• Titanic
• Philadelphia
• The Sixth Sense
• The Passion of the Christ
• Love Story*
• Ghost
• Armageddon
• All the President’s Men
• Amadeus
• Apollo 13
• Dr. Strangelove
• Groundhog Day
• Donnie Brasco
• Hamlet(*)
• Les Miserables
• Schindler’s List
• 12 Angry Men
• A Walk to Remember
• Where the Red Fern Grows
• 2012
• The Last Airbender
• Shrek*
