Supernatural: 10 Perfect Episodes
3. Lazarus Rising
After a mind-boggling cliffhanger in season 3, season 4 of Supernatural started with a bang. Opening with Dean mysteriously returning to Earth having somehow escaped Hell, Lazarus Rising delved deeper into the mythology by adding angels into the mix.
There are many emotional moments in the episode as Dean reunites with Bobby and Sam, and they search for whatever brought him back after the demons claim they do not know. Lazarus Rising is most noticeably known for introducing Supernatural's most beloved character, Castiel. His epic entrance is often regarded as one of the best in the series' 15-year run. Castiel's deep, husky voice added more seriousness and mystery to the character, with fans and Dean himself wondering why the angels chose to resurrect him from Hell.
Lazarus Rising kicked off the angel/demon storyline, which many fans consider the best in the show. Eventually, Castiel would join Sam and Dean as part of Team Free Will, becoming a more complex character as he revolts against the angels and questions his faith in God. In the end, Lazarus Rising will always be a fan favourite episode and one of the best written in the show.
