It's like ST:TNG Season 3 Episode 26 and Season 4 Episode 1.

You had to wait a whole ~four months to see Episode 1 when Episode 26 ended in a "holy shit!" moment on top of one of the best TNG episodes to-date.

If you watch the subsequently, you miss that feeling of build-up; there's no school-yard discussion about what could happen next.

Doesn't keep me from watching it roughly once per year, but the original impact of the cliffhanger was incredible.
