I used to watch this when I was younger, and I loved it. I never realized the Irish music though in the beginning. Maybe that is what sparked my love for it.
My youngest son was in the target demographic for that show. He’s off to the university soon. He grew up with ITM and the more modern fusions of the music in his ears. He really took to that show (as well as “Roar” starring the young Heath Ledger). Mystic Knights helped legitimize the music I played in his mind, or so I rationalized. And some how I thought the show not as mind warping as the Power Rangers. There are still a dozen or so of the Bandai Mystic Knights action figures in his collection. It’s all about the retail follow-ons, innit? One constructive thing came out of his fascination with MKOTNN. We handed him a copy of The Once and Future King and he liked it well enough to become interested in reading similar books although not always in lieu of watching TV.
