Aw cmon! Mars Attacks is incredibly funny...I'm series!
I agree! Mars Attacks is a scream! It's one of my favorites.
There's an entire class of movies... Well two additional classes...
Bad Movies that are still fun to watch... A few examples that come right to mind would be Bruce and Mila in "The Fifth Element," and "Starship Troopers." Any movie with aliens, gunfire, and semi-nekkid women get special consideration.
Then there are those movies that are SO BAD, you just have to love them. Like "Mars Attacks" (although a lot of people would say this belongs in the previous category). And all three Evil Dead movies ("Evil Dead," "Evil Dead II," and "Army of Darkness.")
