Really, they are supposed to be siblings?

Wow, Shannen Doherty and Paul McGillion are supposed to be siblings??

The movie isn't horrible (it's barely good, I admit...) but the premise that those two are siblings is horrible!

I went into this knowing it's just a corny SyFy movie... I wanted to see if Shannen was any good... And I didn't realize that Paul was in it. I love love love him in Stargate Atlantis, so I guess it's worth finishing it just to watch him!
