I didn’t see Hal as annoying, I found Hal as trying to squeeze himself back into a life he hasn’t been a part of for years. His whole life as of late had all been about being a space adventurer, so much so that his last series depicted him hating being stuck on earth when he could explore the stars.
Now? He’s stuck on earth because he bad mouthed the united planets and is trying to find some sense of normality by going with what he knows. Unfortunately what he knows has moved on without him. His inability to understand drones are replacing his field of work, that he doesn’t have any money, and that he’s neglected Carol are playing against his hopes and expectations.
At least that’s how I viewed it.
