3. Leprechaun (Leprechaun 4: In Space)
A franchise about a killer Leprechaun is bad enough (but there are moments in the first 3 that are pretty cool, especially the 3rd movie) but the 4th one takes the cake in stupidity: the idea of a killer Leprechaun somehow making his way to space and trying to marry a princess, etc is just too dumb for words. He wants to rule the universe blah blah and yet they try to make us care. Horror has a history of taking characters and sticking them in space (i.e. Jason X, Hellraiser: Bloodline) but while those had quite a few moments of success (in my opinion), this one didn't need to be made at all. Oh well, we always have Leprechaun in the Hood... uh, on second thought, let's not bring that up.
