Speak for yourself I found the movie to be painful to watch and walked out exceptionally angry.
For me Titanic does rank low.
The AFI has done a “100 Years, 100…” list for the past 10 years. For the 10th anniversary, they went back and redid the original list.
Addendum: the 2005 (film scores) and 2006 (movie musicals) lists only had 25 entries. The rest had 100. (The 2003 heroes and villians list had the 100 split between 50 heroes and 50 villains.)
Give me a choice between “Titanic” “Forrest Gump” and “Under Siege” and I’m gonna watch “Under Siege”.
Granted, none of these three movies are the worst movies ever. But if you are truly going for worst movies ever, wouldn’t they all be B-movies from forty or fifty years ago? It sort of takes the fun out of it if you come up with a list of movies only familiar to MST3K fans.
This, of course, is the perfect opportunity to link to this paper’s own Jonathan Rosenbaum’s brilliant response to this infamous list.
The linked article, and tangents therefrom, is the main basis of my entire film education, such as it is. It’s required reading for anyone even vaguely interested in American movies.
To add to this, the good movies list may judge on the basis of importance, acting, cinematography, soundtracks, etc. The bad movies list can’t just do the opposite, because there really would be no bottom. So instead, a bad movies list must be largely about movies that failed at what they set out to do, artistically speaking. Titanic had an unheard-of budget, big name actors, and lots of hoopla – but it was crap. Yeah, there’s lots of far worse crap out there, but none of that crap had the moolah to work with.
No kidding. How come ten years ago Casablanca was better than The Godfather, but now the Godfather is better than Casablanca? 
Did I miss the release of the superduper editions that change the quality of the films?
Gump was fine. Sentimental, treacly glurge, but not a bad movie. IMO, Titanic was a BAD movie. Kate Winslett was particularly bad - and she has done WONDERFUL work in other films. Yes, it was a wonder to look at, and perhaps it deserved many technical Oscars, but it was a stinker in every other respect. Of COURSE, it’s not one of the 1000 worst movies ever made. In the last 20 years, I bet there have been 20,000 b-movies and cable movies and big-budget spectacles that are worse, just produced in America, forgetting that India is supposedly the most prolific film-producing country.
But it won BEST freaking PICTURE!! AAAARGGGH!
