This is a 2018 remake of the 1980s series Magnum, P.I. (It's almost the same title, but the new show doesn't have a comma.) I feel a certain amount of nostalgia for the old show, though I was fairly young when it was on, and I don't remember much about it, beyond the basics. It's about a former Navy SEAL and Naval Intelligence officer named Thomas Magnum, who now works as a private investigator. He lives in Honolulu, Hawaii, on the estate of a rich guy named Robin Masters, where he serves as a security consultant, though Robin himself is never around. (I don't recall if Robin's occupation was mentioned in the original series, but in the new series he's an author.) Magnum also gets to drive Robin's Ferrari. The estate and its staff are overseen by Robin's majordomo, who in the original series was an amusingly grumpy, high class, old British guy named Jonathan Higgins, who didn't really get along very well with Magnum. (On the old show, as far as I know, we never actually saw Robin, and didn't know anything about him. So there was much fan speculation about his identity, the prevailing theory being that Higgins secretly was Robin Masters. I have no idea if the truth was ever revealed on that show. However, on the new show, we learn in the first episode that Robin is an old friend of Magnum's, so even if we never see him, I don't suppose there's any room for such speculation, this time around.) Another change for the new series is that this time, Higgins (while still British and high class) is a beautiful young woman named Juliet. She still doesn't seem to get along very well with Magnum, though this time around their bickering seems somewhat more friendly than in the old show. And she does end up helping Magnum on his cases fairly often. She's good at that, because she's a former MI6 agent, and pretty badass, as well as good with computer stuff. Magnum also gets help from his old war buddies, Orville "Rick" Wright (who knows a lot of people that can come in handy) and Theodore "TC" Calvin (a helicopter pilot). Other important characters are the cultural curator of Robin's estate, Teuila "Kumu" Tuileta (Amy Hill), and HPD Detective Gordon Katsumoto. Detective Katsumoto really doesn't like Magnum, who consistently disregards his orders not to get involved in police matters.
Other than that, I'm not sure what else to say right now. But I'm enjoying the show a bit more than I expected to. And... it is fun and nostalgic to hear the old theme music again.
