It's hard to overcome just the overall popularity of any given character
and just to stand on it's own merits as a character ALONE.
The legacies of BATMAN, SPIDER-MAN etc. are so strong...well...you know...
Anyways, Hal Jordan has a real Tony Stark/Bruce Wayne
"cool guy" thing going for him---except Hal doesn't have the dough---
and in my eyes that makes him even more "cool" in many respects
than Stark/Wayne.
Between Hal's dense history (which isn't as "big-time" as the top guys
but still "strong") and his overall character/powers---there's a real
good chance that a live action feature featuring "Hal" GL could really
hit a home run.
When I .... how do you say (?) .... think of my mindframe on this spaceplane, I'm Skywalker with my X-Wing like I was when I was a kid.
