In my opinion, the spur of the moment arrival of this documentary kinda shows how important Undertaker has been for the WWE. Also the question is if this was the only way that someone like The Undertaker could put an end to his career. Ric Flair retired and was given a celebration worth a legend like Ric Flair and since they really couldn't give Undertaker the same sent off this was the best way to go with it.
Undertaker could be calling it a career after this and it seems like if this is the end of it for Undertaker then he has more than earned his time to relax and his chance to ride off in the sunset. I highly recommend watching this documentary if you haven't already, because this shows how good WWE is at producing documentaries like this. I firmly believe that this documentary will win awards when it comes to the year end awards from 2020. If this is the end for Undertaker then I will say thank you for everything and I honestly will always remember being able to grow up watching another legend from my time that I had the honor to watch for a lot longer then I should've but that shows how much Undertaker cares about wrestling.
