The way Gil Kane drew Hal Jordan shifted over the years to a wider, more square-jawed face, but if you look at the cover Nerys Myk posted on the previous page you can see how Kane drew Hal's face through the 1960s: it was thinner and a bit less square-jawed than his later approach. But really focusing on the exact dimensions of a jaw and the exact style of a haircut is incredibly nitpicky. Reynolds is a closer fit for his comic book counterpart than a lot of actors cast in comic book movies, many of whom turned out to be very good in their roles despite the fact that their jawlines and hairstyles didn't exactly match the way their characters are drawn.
It's not a question of being nitpicky; it's a question of bringing the character to life. Hal Jordan was always depicted as mature and filled out, and muscular in an old-fashioned weight-training kind of way; Kyle Rayner, from what I know of him, was younger, a civilian and muscular in a lean, jogging or biking kind of way. This guy more favors the Rayner type.
Back then I was skinny little kid who played astronaut using Matt Mason dol....er, action figures.
