The final season felt very disappointing to me. I felt the acting of a few characters to be more dramatic than in previous seasons. Each episode was unnecessarily stretched out to 40-45 minutes and I couldn't feel any high/emotional moments as compared to previous seasons, except for the last few minutes of the final episode will was a bit emotional. It felt like everything was made in a rush.
SPOILER ALERT
I still wonder why the makers decided to plan a scene to randomly end the character of one of the resident doctors. I felt the outcome of the incident, the grief of loss, or the whole plot to end character could have been written well. Earlier in the series, one of the senior doctors collapses and loses his life in a tragic incident - The entire plot was staged perfectly and the viewers were able to process the emotions one by one. As a viewer, I was able to relate to the incident and travel with the characters while they were processing their grief.
