When I think of title sequences that really set the tone, I can’t help but think of The X-Files. It sells the genre so well, and the music is a real ear-worm.
Fringe, considered by some to be The X-Files’ spiritual successor, did a bit more with its opening titles, adapting them as the seasons went by to serve as visual anchors for the viewer. The colours, the text, and even the time style, all told us which story universe this episode was centred around.
