"I can't believe the writing is trying to make Robby look good!"
Bro is screaming crying throwing up and wallowing in suicidal thoughts, bro is not looking good to anyone. He's yelling at his employees, snapping at people, projecting his issues, and dodging every single person trying to make him talk it out. He's clearly in a downward spiral. He's looking as bad as he is, it's rough to watch.
He's just also a dude who is really good at his job even when he's crashing out, which is staying true to the character we were introduced to in season 1. He's also acted out excellently by Noah Wyle, sending us on painful face journeys each time Robby's confronted.
The show asking us to feel empathy for Robby isn't "making him look good." Like Wyle and the other writers have said, it's making a point about the struggle healthcare workers have and how the people around them and society at large react to it. Robby isn't the only storyline in the show handling that, but his is the most prominent, being the most prominent character. Maybe have a serious think about that if you insist on watching The Pitt but can't handle "the Robby show."
It was always the Robby show, by the way. We were following him closely in season 1. We only had some distance in season 2 because the aforementioned crash-out until we got the final few episodes. It's going to keep being the Robby show, it might be seven seasons of the Robby show. Remember, we know the thesis of season 1 was "the doctor is the patient," for season 2 "doctors don't make good patients," and season 3 has the promised "doctors benefit from being patients." Those theses directly reference Robby's journey.
So buckle up or get off the ride.
