Here's a thing I ain't heard yet. I know a lot of decent kind and good looking young lasses, not in the biblical sense, you understand. Not that way inclined.

I'm a teacher. Part time, voluntary. Etc.

Fact is, lotta of em a bad boy. I see perfectly decent young lasses hanging around with arseholes destined for jail, or gaol. Eejits I say. But the loins decide their own path. No matter what you say, they love that dickhead. If fact they love them more when you try and put them off. Especially when you're off limits.

The heart and the head are diiferent. You get that in a script proper and you got a winner.

Ren rests. Night all. I've gotta stop watching the wheels and listening to working class hero. For tonight at least. My candles are dead. As is my bottle. Barstard. Must be time for bed. RV out.

It's okay for the character to be unlikeable, so long as he has a saving grace.  Some examples:

Jack Nicholson, As Good as it Gets -- a total prick in every conceivable way -- but he's a humorous prick, and you see him catching himself in the act of being one and can sense his regret at his inability to control it.

Mel Gibson, Payback -- a brutal, ruthless thug -- but his drive and indominitable will, coupled with his obvious love for the Maria Bello character and the fact that despite being offered more he wants only what is due him, humanizes him.

Pulp Fiction is littered with despicable characters but Tarantino fits them with senses of humor, philosophies and certain contradicting moralities which make them interesting.

In Asian films are some of the most despicable and unlikeable characters you can imagine -- but Asian culture has one rule for their anti-heroes.  As long as the character is true to himself and does what he does because he absolutely believes it's called for, a character can literally get away with murder.  You have to juxtapose his outward ugliness with an inner strength, or, contrarily, some inner flaw beyond his control which explains why he is the way he is.  

Don't forget that you have to romanticise and fictionalise. That's what movie making is about. Take Braveheart - even Mel Gibsom said that the hero in reality was not a nice man, but he was romanticised and fictionalised for the sake of the movie. I agree with the earlier poster - is it a hero or antihero?
