I was talking to a musician pal about this and how the iconic TV intro is a lost art. Mad Men kinda had it, something we really remember, but so few do. I asked him why TV themes didn’t stick with us so much anymore and he reckoned the John Williams era guys who went brow in the 60s were inspired by the 40 jazz numbers they grew up with, which were super-catchy. Since mid 80s it’s all been very generic and I think that extends to credit sequences too.
This isn’t a particularly good one (I think The Equaliser intro was the last really great one), but it’s really interesting and mental. An added bonus is that the voice over is Winnie The Pooh, also Kaa the snake from Jungle Book, of course.
