Yes, I hate bad ends. Nothing new you will say, or think, and I am not very original by saying that, but the fact is that I've been reading 2 books and both of them had bad ends.
When I say bad, it does not mean that it was not a happy end or something like that. It was bad because it looked like the authors stopped writing their book in a hurry to give him to their editors and just put a point to the story, with a lot of pending questions or just the laziness to go deeper in their thought.
Some may call that "suspens", other will say that it lets the reader think about the options, and reinvent the story and the aftermaths of the climax and anticlimax.
But I hate that.
Hopefully, the first story of "Killer Koala" was fun and the end was good. Alcool and snakes don't go well together !
