I first get to know about the series through a YouTube short. This show is really addictive. I wasn't been able to stop watching it since I start . I literally finish all four seasons in a week. It was so good. The relationships between the characters, the cast is brilliant . They really give their all to the series. This series i a emotional roller coaster. Can't wait for the season 5 . I really recommend this series to people who likes to watch medical scenes and emergencies and also TK and Carlos their chemistry is out of the world. All characters add their unique charms to the series. Love it so much.
