Manga with terrible endings

[B-BooXx]

I saw the thread on mangas with good endings and thought we should discuss those with terrible endings.

I have finished 2 series in the last week that had terrible endings:
Junai Labyrinth
Kakan no Madonna

Especially that second one [spoiler]At the end when that dude who we haven't seen for the last 10 chapters dies and that somehow ties everything into a neat little bow[/spoiler]

Anything half-assed. Like Panic x Panic. It's only 2 volumes, and the first had such promise, but the second was like "pah, I spit in your face."

To be honest I really didn't like the end of Vampire Knight for this reason. it was like "shit, I'm meant to end it this chapter, how do i quickly sum up all the character plots in the worst way possible"

[QueenyLeAcH]

Bleh.

[Disturbance]

Agreed. Vampire Knight was horrible.

I think I stopped reading that one after volume 5.

A LOT. I can't even count how many mangas I've finished that has a terrible ending, although some of them has good plots and characters. Man, that was a waste.

Agreed, however thankfully the good outweigh the bad in general
