Six Feet Under is turning 15 this week, so HBO is celebrating the milestone by airing all 63 episodes on HBO2 beginning Thursday.

The drama, created by American Beauty writer Alan Ball, follows the fictional Fishers — played by Peter Krause, Michael C. Hall, Frances Conroy, and Lauren Ambrose — as they run their family funeral home while dealing with the loss of their patriarch (Richard Jenkins).

The series nabbed multiple Emmys and Golden Globes over its five season run, which began on June 3, 2001. The much-discussed series finale aired Aug. 21, 2005.

“I remember when I wrote this episode I cried,” Ball said of that final hour during a Q&A at this year’s Tribeca Film Festival. “Pretty much the last four episodes, people were crying all the time. But it was good. It was grief. It was letting go of something, and I think it informed the show in a way that was very organic because the show was about people who help us to face our grief. It was pretty cathartic.”
