While most episodes of ER are as fascinating as the field of medicine itself, there are a select few that are truly iconic television. The '90s series is widely considered the best medical drama and no matter how much time passes, its smart characters and life-or-death scenarios remain as meaningful as they did when the show first aired.

Every fan has their own personal favorite episodes that they like revisiting when in need of a comfort watch or because they want to see an intense plotline unfold all over again.

However, these ER episodes are so beloved because they're a solid season finale, introduce an important new Cook County General Hospital employee, or feature a devastating medical case that still resonates.
