Here’s an odd take. Aspects I liked for Hal: getting drunk in Emerald Twilight, getting with Arisia when he shouldn’t have, getting grey hair to show his age. Even becoming Parallax. All made me like Hal as he wasn’t flawless or white bread.
But they spent the last 15 years retconning each and every one of those aspects.
Post-Rebirth Hal is almost like a different person. As different as Spectre Hal.
