I'd like to see the show return to a format more like they used in the beginning.
It used to be a show about young doctors treating interesting patients, performing difficult operations, and, yes, making mistakes (but learning from them). That was the core of the show. The interpersonal drama just flowed along with that. Of course, there was romance and there were problems between some of the interns, etc. But at the end of the day, it was a show about dedicated people whose main focus was making sick people better.
Now, they don't seem to 'waste' much time on patient care and surgeries. Now, the show seems like more of a soap opera, with its main focus about who's together and who's breaking up (and why). The hospital is mostly just the stage setting, now, and the patients they treat are usually just playing minor parts.
