#1: The Undertaker explained how he finally came to peace with retirement
Throughout this five-part docuseries, The Undertaker talked about how he kept searching for that one perfect match to end it all.
In a way, The Deadman kept pushing for one more match despite meeting with disappointment several times in the process. He envied the fact that Shawn Michaels had made peace with letting go of this industry at the perfect moment, and The Undertaker finally found his own peace after learning life lessons throughout the last few years of his career.
From WrestleMania 30 to The Last Ride documentary, The Undertaker's final phase of his career has been a 6-year long arc. It wasn't just the excellence of the Boneyard Match that allowed him to retire, but the docuseries displayed how Mark Calaway finally eased into his role as a family man.
The desire to have "one more match" is no longer a huge part of his life. After all, Mark Calaway has found a separate calling as a faithful husband and a loving father.
Of course, he may come back in a small capacity if Vince McMahon really needs him, but the character of The Undertaker has finally completed its arc, and Mark Calaway also found peace in the multifaceted nature of life.
The Undertaker's retirement isn't a sad moment at all, as a matter of fact, it is a moment to be celebrated because both Mark Calaway and The Undertaker got a perfect ending they deserved.
