What Bush’s Casting Means For Grey’s Anatomy Season 21

Grey’s AnatomyCould See A Rating Boost

Known for her role inChicago P.D., another major network television series, she is a well-known TV actor. Bush has quite a rich history on television that goes far back toOne Tree Hill, where she portrayed Brooke Davis. However, it is not her first time portraying a physician on television,having not long ago led the medical dramaGood Sam. However, the series was canceled after just one season due to low ratings. Nevertheless, her casting inGrey’s Anatomymarks her return to the medical genre.

Amelia can finally honor Derek through “impossible” surgeries in Grey’s Anatomy after her and Meredith’s Alzheimer’s research made Derek’s obsolete.

Once Bush joins thecast ofGrey’s Anatomy, it will be interesting to see how the show’s ratings are affected.Grey’s Anatomyis releasing in a busy fall, with other major network shows including9-1-1,9-1-1: Lone Star, andFire Countryall having concurrent active seasons. With such a stacked lineup, procedural series likeGrey’s Anatomyneed something to help them stand out. Bush’s casting may be the push season 21 needs to maintain audience interest.

Why Bush Is A Good Choice For Grey’s Anatomy

Bush Has Past Experience In The Genre

With all the pushGrey’s Anatomyhas been making lately to focus on a broader set of characters, I think Bush might step in to become a more significant lead. However, it’s unclear if she will continue the role in a greater capacity into season 22. Nevertheless, with the actor’s vast experience, I couldn’t imagine a better person to take on the Cass Beckman role.
