Twin Peaks must be the best one for me. I never got to see it when it was new (too young), but happened to hear the intro music and opening shots before my parents switched the channel. That minute stayed with me till I was in my late teens and bought the show on DVD.

The worst? Maybe Sex and the City, but that’s also because I find the main characters self-centred and morally repulsive, which the intro communicates quite efficiently.
