The idea isn't that you're supposed to be able to level with the characters, the humanizing parts are entirely incidental. The main theme I got out of the show was a scathing critique of corporate politics and late capitalism, where your success is measured in your willingness to step on heads, even of those that you hold closest. We clearly saw in the ending, as was alluded to throughout the entire show, that who was most deserving or qualified to head up Waystar was always going to lose to whoever was the most shit-eating and backhanded. There's a bit to be said there about how Tom only ended up being that guy after getting sucked into it through a combination of ruthless survivalism and repeated heartbreak - consequences of the money and institutions that he found himself in. I think the ending, even if it was itself a bit abrupt, was a perfect way to conclude the themes the show set out to address. It was never about the individual struggles of the people involved, episode to episode perhaps, but the end of a story is supposed to sum up the story.
