mine was this http://www.imdb.com/title/tt0404756/ alien apacalypse, you have to watch it to understand why it's so cheesy.
Wing Commander - but loved it and the game when it first came out
surely it has to be...
plan 9 from outer space by ed wood?
Haven't heard of any of those movies.
Wait leprechaun I have watched.
Leprachun 4: In Space, definitely LOL.
Alien apacalypse is also pretty cheesy, I'm surprised no knows about, guess not everyone stays up till 4 am watching the sci fi channel( I know its now called sy fy).
Well, most famously, I watched Santa Claus Conquers the Martians.
I don't even know, Santa clause in space, probably the worst movie ever made but I've bieber heard of it.
Mega Shark vs. Crocosaurus.

Sharknado made me laugh hard due to its cheesiness.
Mega Shark Vs Crocosaurus was also one of those movies too...
Dragon Wars, good god so bad... Let's just say a man gets hit by a car and turns into a Power Ranger of some sort.
