That's a good question and a fair point, and part of the reason I waited until the end of season one, because he does make a bit of a transformation in the last episode of that season when he sees that being miserable to everyone all the time is not making his life any better. So there is some growth there, especially as relates to his relationships with the key people in his life, and it changes the dynamic in a good way.
That said, I have now finished season two and am one episode into season three (the final season) and I told my wife the other day that I'm getting a little tired of his inability to snap out of his depression. She told me to "just wait" because she has already watched the entire run, so I am reserving judgment until then.
And so far it has stayed relatively formulaic, with each episode seeming to end with him watching videos of her and crying. I don't love that formula, but I like enough about the show overall to see it through.
To be clear, it's not as good as either "Curb Your Enthusiasm" or "Ted Lasso," but those are two of my all-time favorites and they are very different from each other, and I like that this touches on elements of both of them. He's as miserable, obnoxious and direct as Larry David, but he's also broken like Ted Lasso, and deep down you know he is a good guy who can help make others' lives better--if he can just get out of his own way.
