Well my vote goes to Armageddon, and I'll explain.
- Armageddon is not the worst science I've ever seen, but it is the worst I've seen in a movie that was billed as being scientifically and technologically accurate. There was an article published in Smithsonian Air & Space magazine prior to the movie's release that hyped it up as being a realistic depiction of an asteroid disaster and a manned rescue mission. They claimed to have NASA personal consulting on the film and all that. All that turned out to be BS.
- Armageddon is, in addition to being full of bad science and tech, just a very bad film. The story was silly, the script-writing was awful, the acting was awful (can you say "Ben Affleck?), and the music was horrible, TV movie music. The pacing of the story, with it's multiple false endings, made me want to stab myself in the eye with a pencil. The only reason I didn't walk out is because the people I was with liked it. Which brings me to...
- The wrong people like this film for the wrong reasons. They think it's realistic, and they love the flag-waving patriotic hero crap. These are the kind of people I just can't identify with. They always use the excuse, "It's just a movie." By that standard there are no bad movies at all, because they are all just movies.
It's just a bad movie. It's the Michael Bolton of movies. Everybody knows it sucks, but somehow it still has lots of fans.
