This is not a great question but I use a lot of cliffhangers. And I have a habit of making cliffhangers in the end of every chapter that I write just to hook the reader. The question is, is it a good idea? Won't it look monotonous after a while into the novel?
Ending each chapter on a cliff hanger is a plot device used in some genres, like thrillers. Dan Brown uses it extensively in his books, as do some other writers. If well done, they can make the book more exciting, and gives it that 'can't put down' feel.
On the other hand, if done badly, it irritates the reader, as it seems the only purpose of each chapter is to put the hero in even more trouble. Also, if your characters are boring, the reader might just say, go ahead and die already. Certainly I've thrown away books where the hero was getting caught by gun toting henchmen every five minutes, just so each chapter could end in a cliffhanger. And this was in the first 3-4 chapters.
So, I'd say no, they should not be used in every chapter. My advice (as a reader, as I have no experience as a writer writing cliffhangers) is:
If not sure, put your book away for some time and then read it as a reader. Do you feel the cliffhangers make the book enticing, or like a soap serial, their only purpose is to get you to the next week / chapter?
Proper tense cliffhangers should be kept for a few occasions, otherwise your readers will guess what is happening, because they know it needs to have a problem by the end of the chapter. Like Eastenders.
However leaving the ends of chapters in limbo - unresolved, with the characters walking off to certain death, while you take up another thread of the story will have a similar effect, of keeping the readers going and wanting to know what is going to happen to them.
At the same time, resolving everything raised in a chapter during that chapter is boring, as there is no sense of long-term development of the characters and situations. Sometimes, you just need to move the characters on in a chapter, and prepare for something later.
I would say no. Not for a book.
Regardless of how you are defining cliffhanger, I don't think you need an aaiiigh!! moment at the end of every single chapter. A chapter should end for a reason, but that reason doesn't have to be a shock, reversal, discovery, or threat to life/limb/happiness.
If you use the same trick or tool repeatedly, in the same place or the same way all the time, it gets old. Your reader becomes jaded. You wouldn't use the same sentence structure over and over, right? You mix it up. So why use the same narrative tool?
Soap operas and lengthy serials need cliffhangers because the story never ends. You need a reason for the audience to keep returning. A book is pretty much by definition a finite narrative. (Even reeeeeeally long ones like A Song of Ice and Fire and Lord of the Rings.) At some point the story will come to a conclusion, and you hope your reader will complete the journey with you, so you can afford to end an internal arc because the larger arc of the entire story is still going.
If you have a neverending story, then you have to use cliffhangers to drag the audience along, because there's no quest to finish. There's no The End coming — you have to give the audience something to come back for.
Monotonous cliffhangers seems like an oxymoron.
In principle, I'd have no problem with consistent chapter-ending cliffhangers, provided that it didn't get overdone. After all, pretty much any literary device can be overused.
In this case, overdoing it would depend more on quality than quantity. The more you use a literary device, the better you'd be at using it, lest it become worn and trite. If these cliffhangers are forced, corny, cheesy, or contrived, then even every third chapter would be too much. But if they provide a natural, intriguing, riveting free-flowing transition into the next chapter, without being repetitive, why not?
So, would a cliffhanger at the end of every chapter constitute overuse?
