Most of the characters on Grey’s Anatomy, such as Cristina Yang, Meredith Gray, and Derek Shepherd, enjoy the love of fans. However, Penny Blake, played by Samantha Sloyan, did not share the feelings experienced by other characters.
For one thing, Penny didn’t manage to stay long as a cast member of Grey’s Anatomy, she only managed to appear in just 2 episodes of the TV show. Likewise,
Penny made her debut on Grey’s Anatomy during season 11, the episode where Derek exited the show after Derek was in a car accident, taken to Dillard Medical Center, where she was a resident.
Recall that Penny was in charge of treating Derek, she pointed out that they should do a CT scan, but the superiors ignored her, so many thought it would be the last time they would see Penny. Later in the show, however, Callie Torres (Sara Ramirez) introduced Penny as her girlfriend.
Things took a turn when the resident transferred to Gray Sloan Memorial Hospital, and was placed under Meredith (Ellen Pompeo), the fact that Penny had something to do with Derek’s death caused a lot of problems when working with Meredith. But eventually, Meredith declared Penny indulgent, at one point even letting her help with a kidney transplant.
In the end Penny (Samantha Sloyan) applied for a grant that would lead her to move to New York where Callie and Penny later agreed to move in together. The deal led to Callie and Arizona Robbins (Jessica Capshaw) having a custody battle for Sofia.
In the season 12 episode “At Last” of Grey’s Anatomy, Penny exited the show. The main reason fans hate Penny is because of the role she played in Derek’s death. Another reason he didn’t resonate with fans is the role he played in causing the custody battle for Sofia.
Penny’s character (Samantha Sloyan) didn’t get a chance to get the love of fans. Her part in Derek’s death was something fans hated her for and couldn’t forgive from her very first episode.
Maybe some Grey’s Anatomy fans love her, but no one can hear them amidst the many enemies, even if they exist. Most fans feel like she shouldn’t have been on the show in the first place because they consider her a really weak plot pointless character.
