Well, The thing is: I first reading GL's comics was Geoff's run and really liked the characterization of his Hal.
But when I become a hal fan and trying to read more about his comics, Find out Hal's characterization(Geoff) has big difference from his previous characterization, For example: Geoff's Hal always question the authority and Sinestro really impressed by Hal this trait, But before Geoff, Hal has been portrayed respect the authority and Sinestro not really likes or respects Hal like Geoff's version
So I wondering What is your first impression about your favorite character(s)? Sometimes I think it is really interesting a character could have different characterizations in different writers.( Though sometimes, When a bad writer portraying the character you liked, It will really make you want to drop the comic)
