Compare to the Book...
The Fifty Worst Films of All Time (and how they got that way).
Harry Medved wrote this book in 1978 (when he was 17). There are so many more non-deserving films in this book than in the DVD.
Tastes must change over the years, but between 1978 and 2004 there are three worst films that are still on BOTH lists:
http://www.imdb.com/title/tt0055946/ Eegah!
http://www.imdb.com/title/tt0072317/ Trial of Billy Jack
http://www.imdb.com/title/tt0058548/ Santa Claus Conquers the Martians
Best and Worst:
50 Worst Movies
Spider Baby (7.0)
Hillbillys in a Haunted House (1.5)
50 Worst Films
Last Year at Marienbad (7.9)
Eegah! (1.9)
Ratings based at the time of this writing, of course.
