If you don't have a person handy to do this to, try going to YouTube and searching for "[your favorite piece of media] reaction".
It's really easy to find folks reacting to music, and there are also some folks who do reaction videos for movies, games and shows.
You can never experience watching your favourite show for the first time again, but you CAN convince someone else to watch your favourite show and vicariously enjoy all their raw reactions to seeing it for the first time, which is honestly nearly as good.
