I saw Burn after Reading. I didn't like it. Why? Because the characters were unlikable.
Now, that's not to say I'm one of those people who likes the typical PG story where we're all rooting for 1991's John Cusack to get the Girl. That's just to say that you need to have something else if you're going to have characters who are unlikable.
This is a part of why "It's Always Sunny in Philadelphia" is so good. Sure, the comedy is great, but the fact of the matter is we've all tried to put one over on our friends. And it's exciting.
I am going to rise up and kick a little ass, gonna kick a little ass for the USA. Because I like unredeemable chracters. Yay!
