If you ever watch the movie "Edges of Darkness" you will know the answer to this question. NOT the really bad Mel Gibson "Edge of Darkness", this gem is on it's own level of horrible.
I would say that some musical films are really bad (like High School Musical ones) and I think some older science-fiction films are bad too (I am not saying Star Wars is bad, I like it.)
The old Tron. And we mighst as well throw in the New Tron as well. The affects were bad, and the story dragged. I fell asleep mid-way through the new one, and after seeing the preview for the old one...
Water World as well, seeing as its a complete waste of 90 minutes.
I thought that AVP (Alien VS Predator) was awful, I don't watch films unless a friend of mine recommends or I liked the book, but that film was just brutal.
I didn't bother with researching bad films. So, I just looked on my DVR at the films that I have already recorded. And I must say, 'Monster's ball' has to be the worst film that I have recorded.
I didn't like how it was poorly made and the story behind it is horrible.
Only thing to the movie is that a lady's husband gets executed, her son dies by getting hit by a car, she gets seduced by a racist white man, they live happily ever after.
I think Scooby Doo the first movie in 2002 but Scooby Doo 2: Monsters Unleashed in 2004 was better. Both are worst movies. And I love the Old Animation better than New one!
