Annabelle asked a question

I've just read a manga, the beginning was quite cool, I was thinking that it was a manga different from others and then... End of the 8th chap, in one page, it became so messed up. I checked how many chapters the manga had, and when I saw there were 9 chapters, I understood.
Do you guys know too, those mangas that have a cool beginning but you suddenly feel that the story is rushed ? It's like the author was said " Hey, you did a good job while well-developing the characters and the story line, BUT you have only one chapter left to finish the manga, good luck (⌒▽⌒) ". And with this, the manga goes from really cool to... non-interessant and wasted.
It's not the first manga I saw with this problem and each time it makes me SAD. ╥﹏╥
