Including terrible films starring John Cusack, Jane Fonda, John Travolta, Will Smith and Jon Voight, here are the ten worst science fiction movies of all time.
They are (apparently in no particular order):
Barbarella (Roger Vadim, 1968)
Piranha 3DD (John Gulager, 2012)
Alien vs. Predator: Requiem (The Brothers Strause, 2007)
Highlander II: The Quickening (Russell Mulcahy, 1991)
I haven't watched it, and I'm Brazilian, but I'll defend Brazilian Start Wars anyway. I'll basically defend [any nationality] Star Wars actually. [any nationality] [any popular franchise] needs to be a genre.
I looked it up after commenting. It's a Trapalhões movie. I probably watched it as a child. I don't know how or when you watched it, but I would have to defend it for historical reasons. It's the first movie with the four comedians that formed the main group together. The special effects are awful for being filmed using videotapes and sending them to the USA for transferring to 35mm (an illegal act at the time). They are clowns, as in circus clowns making cinema, which informs a lot of the comedy.
All that to say, as before, it's good dreadful, something not everyone even believe exists.
I double checked this one. The weird thing is, Cloverfield was released as Monstro in Russia and Ukraine, Project: Monster in Poland, Monstrous in Romania and Bulgaria. I've yet to hear why, but I guess it's eastern european distributors rightfully thought this name would be more telling of what's presented in the movie.
