Well, that is a crazy thought, Dano--if we are to go off the trailer (which is all we've got). Because it certainly appears from his lines, that they've written his character to be cocky and cool.
"I've been running scams on the streets since I was ten."
"I was kicked out of the flight academy, for having a mind of my own."
"I'm going to be a pilot. The best in the galaxy."
"That's yes."
"What's that?"
"Thought we were in trouble there for a second, but it's fine. We're fine."
So no, the character *is* a cocky and cool badass in this script.
The problem is, the actor can't pull it off. And that is why for the first time ever, I daresay, a trailer for a Star Wars movie was booed by a theater audience.
