I was just pointing out that people in this thread, including myself, were saying the exact things you said you find disingenuous. It's not that there aren't people that do what you're saying, but saying you don't believe anyone that says that in a thread where people are saying that exact thing comes off a little insulting.
Yes. In my mind, it always comes down to execution. Some ideas just might have more challenges, but in my mind almost anything can be done - it's just about how they go about it. I love "cocky, confident Hal" but some writers make him look like a dick, while others are able to write him as awesome. Same brush, just different techniques.
It really comes down to how a writer understands confidence. Too many people think it's macho posturing when the opposite is true. In my experience, the most confident people are the ones least likely to be trying to prove how awesome they are.
It was the key difference between Hal and Guy back in the day. Guy was desperately overcompensating because he didn't actually think he was the "Greatest GL" whereas Hal felt he had nothing to prove and was much more chill.
That said, I think Johns's more over-the-top characterization also made sense because of where Hal was at that stage of his life, finally redeemed from his crimes as Parallax, but still hiding the guilt for his part in it buried under a lot of cocksure braggadocio.
And, emerging out of Johns's era, we have Morrison's Hal, who's regained his old confidence and has nothing to prove to anyone, particularly himself.
It will be interesting to see where Tamaki's Hal lands on this. Hopefully, we don't get a reversion.
