I never thought of making a top ten worst movies ever but this one for sure is going to make into the top 3 of the list. Plot summary from IMDB:
Martians, upset that their children have become obsessed with TV shows from Earth which extoll the virtues of Santa Claus, start an expedition to Earth to kidnap the one and only Santa. While on Earth, they kidnap two lively children that lead the group of Martians to the North Pole and Santa. The Martians then take Santa and the two children back to Mars with them. Voldar, a particularly grumpy Martian, attempts to do away with the children and Santa before they get to Mars, but their leader Lomas stops him. When they arrive on Mars, Santa, with the help of the two Earth children and a rather simple-minded Martian lackey, overcomes the Martians by bringing fun, happiness and Christmas cheer to the children of Mars.
