But that's almost the complete opposite of Hal's character in the comics. His father's death was traumatic, yes, but it was also inspirational to him. He became determined to be the best man he could be, and to follow in his father's footsteps, even to the detriment of his relationship with his family. He wasn't hiding his emotional baggage, he embraced it.
Not as Geoff Johns tells his origin. It was something that he worked through; his tendency, as he admitted to his youngest brother, was never to be there for anyone and to harbor deep resentment against Carol's father.
Johns has also pretty thoroughly dumped the "without fear" anger in favor of "you have the ability to overcome great fear," another improvement.
