Respectfully, I think she’s the least passive aggressive chief stew in the history of the franchise. She’s no bullshit, is good at her job, works her ass off, is kind and fucking hysterical in the process.
Also, the only two criticizing her were the two who were fired, and neither of them were in a position to say anything about anyone, especially Ryan.
That said, I did think Aesha was annoying as Hell the 4th season of Med, but then found her to be the only redemptive quality for the short time she was on the 5th.
