Ironically, some comic fans will tell you that "the powers that be" injected more life into Hal by making him "funnier" like Kyle Rayner and "Batman's punching bag" like Guy Gardner.
Kyle was the boot leg Peter Parker cracking jokes and Guy was the cocky dumbass who would get sonned... but when they brought Hal Jordan back to life in the mid-late 00's, they wanted him as 'the man' and infused a lot of the characteristics that defined the other two. So he basically has 3 different personalities now depending on the story arc.
They switched out the Flash character too. So he's not the "funny" one (red head Wally) but the 'boring' serious one (blonde hair Barry). In fact, as far as least dynamic goes.. superman, green lantern, flash, wonder woman, and aquaman could all be pretty generic depending on what they do with their character.
Take Wonder Woman, in previous incarnations she is this peaceful mature ambassador.. but in the recent Justice League movies, they made her this fight first, temper tantrum having would-be killer. They spiced her up. They'll take whatever liberties with any of the characters, which is why i'm not concerned with any of the ______ is boring stuff.
