I Can't Believe This Exists

So I was wandering through IMDb -- one of my favorite websites ever, in case you didn't know -- searching for Vampire Hunter D to see if it was worth seeing, and this came up in my search results.

I looked once.

I looked again, because it was too totally unreal.

My eyes were not tricking me.

There really is a movie called "Jesus Christ Vampire Hunter." And yes, it is a musical -- because what else would a movie about Jesus Christ killing vampires be? The tagline is as follows:

"The first testament says 'an eye for an eye.' - The second testament says 'love thy neighbour.' - The third testament ... Kicks Ass!!"

I don't know whether it's any good. I seriously doubt it is. But I absolutely have to see it, if only because the title makes me laugh just thinking about it.

So, question: What is the one movie that you knew for a fact was going to be bad, but had to see anyway? And the follow-up, why did you have to see it?
