Forgive me for double-posting, but you can't talk cliffhangers without this guy, so I have no choice.
After all, resistance is futile. Article is still
here.

If you need it, there's an episode summary, with air dates and some wicked anti-spoiler devices(damn straight!)
here!

Not sure I agree with the rest of the list. Angel in particular had a couple better cliffhangers than the one they chose. And so did Lost.

As for the list, no one will ever agree with everything, but it does say that they only allowed one cliffhanger per show, and it specifically mentions that they did that so that Angel wouldn't be in every slot. Having never seen Angel, I can't speak to that.
