The dirty secret about cliffhangers is that they work.
Whether they’re corny, cheesy, clichéd, obvious, predictable or downright contrived.
Sure, you may well get called a hack and a cheap manipulator, but cliffhangers only guarantee the reader will cross the chapter break, they don’t guarantee they’ll like what they find when they get there.
Obviously, it would be preferable if writers used this technique for good instead of evil. But we all know that's not how cliffhangers are used for the most part. Anyone with a television set can see the abuse and misuse they are put to nightly. Still, it’s worth having this weapon in your arsenal. How you use it is your affair.
