Well here's a quite run down of 5 for each catergory.
Good: The Dark Knight, Animal Farm (Animated Verison), Twice Upon A Time, The Blob, and Dick Tracey
Bad: Troll, Eight Legged Freaks, Raggedy Ann and Andy: A Musical Adventure, Cool World, and Kingdom of the Spiders
Ugly: Jaws 4, Monster A Go Go, Street Fighter, Beware! The Blob, and Titantic: The Legend Goes On
Mostly the ugly list are movies you should see just to believe that they actually exist.
Ok, this is NOT something you must see before you die, but Street Fighter triggered a memory...have you seen the previews for the new Street Fighter? With Kristin Kreuk as Chun Li and Neal McDonough as M. Bison? I suppose this would fit more into the WTF moments...
