I love it. Once again, you have a great set up for a movie. If it was to make the big screen though, you'd probably have to give it a happy ending. While I love this kind of resolution, American audiences generally want stories to end well for the humans. :-)
Well, the man that came didn't die at the end ...(At least not yet) - does that count as a happy ending?
Quasi-happy... :-D
I'll take it!
