I fairly recently suggested an older TV series to a coworker I thought would really like it. He’s loving it and comes in almost every day talking about all the different goings-on in the new episode or two he’s watched. I saw the series about 20 years ago, when it first came out. Without giving a hint of any spoilers, I’ve been able to consistently give him alternate viewpoints and ways to frame things he’s seen, which has given him a much deeper appreciation of the show while still keeping the upcoming twists and amazing reveals a complete surprise for him.
