There are only two on your list that I have any desire to ever watch again.
However, there are many 1970s movies that I will watch again:
Dirty Harry, The Cowboys, A Man Called Horse, Jeremiah Johnson, The Life and Times of Judge Roy Bean, Blazing Saddles, Rooster Cogburn, The Outlaw Josey Wales, Patton, Tora! Tora! Tora!, The Great Santini, Alien, The French Connection, Monty Python and the Holy Grail, Serpico, Young Frankenstein, Animal House, Deliverance, Willy Wonka, The Man Who Would Be King
My Name is Nobody, They Call Me Trinity, Trinity Is Still My Name. Add to that the Bronson movies and movies Burt Reynolds did. Burt was on Fast and Loud the other night. The years of stunts had causght up with his body.
