A Movie Plot:
Imagine this movie:
The main character is a young man without a whole lot of prospects. Living in the shadow of his older siblings and with no real likelihood of getting/inheriting anything on the home front, he heads out to make his own way.
Naturally he meets a girl and they immediately connect. They seem like a perfect match. But of course her family disapproves of their whirlwind romance.
Determined to make it all work out the hero starts manipulating things. He's doing a little deceiving and he's working all the angles. He's got a lot of balls up the air and he's managing to keep everything in motion. And while what he's doing isn't exactly on the most honest and straight and narrow of paths, his heart is in the right place. He has a girl to win and a fortune to claim.
Of course things start to spiral out of control and then just as it seems there is no way he can pull it off, ***** everything comes together. The girl is his and he's made a name for himself.
Perhaps at this point you are saying, "Mister B, this is not a very original movie plot."
Well you would be right. There are countless movies that follow this general script. Off of the top of my head: The Secret of My Success, Some Kind of Wonderful, Opportunity Knocks, 10 Things I Hate About You, etc, etc, etc. Really just about every other movie made in the 80's
Okay, now go back to the place marked with the five asterisks (*****) and change the ending. Scrap everything after that point and change it to:
everything gets worse. The more he tries to keep it together the more things spiral out of control. The more they spiral out of control, the more frantic he gets. In the heat of the moment he starts making some bad decisions and before he knows what's really going on, he's stepped a bit too far over the line. Instead of the hero of our plot, he's the villain.
I've just described Hans from Frozen.
The more I watch this movie  the more I feel bad for him. One little twist of fate in the other direction and the credits are rolling, everyone is happy and he's got the girl.
Yes, I know. You want Anna to end up with Kristoff. That's only because you've seen the movie as scripted. You've seen the wheels come off the wagon. But you can't deny Anna and Hans have a connection at the beginning of the movie. I don't know about you but I've never met someone before that I could immediately sing a complicated duet with.  They were BOTH singing, "You and I were just meant to be."
If there was no Kristoff and the movie was scripted differently, you'd have been cheering at the end when they ended up together.
Just saying. 
Hans : B-
 - Note this place. It will become important later.
 - It's the Bean's favorite. We watch it and/or listen to the soundtrack a lot.
 - Not even the Pook.
 - Yes, I know he tries to kill Elsa with a sword. At that point, everything is so chaotic and out of whack he's been taken over by temporary insanity. You may be laughing now, but there are plenty of real world stories (and movie stories) in which someone gets caught up in the moment and takes things one step too far without really realizing how far over the line they've managed to get.
 - Either a victim of bad luck or perhaps just simply on the wrong side of that Disney Magic.
