Normally I'd cut the author some slack when their series gets axed and they have to hurry up and finish everything they started prematurely, but in this case the entire drama was literally started in the last two chapters after the end date was set in stone.
Like, I totally get having to abruptly cut off something that you don't get the time to do properly (Bleach REPRESENT!), but why on earth start something when you know you only have 1 more chapter to wrap it up and it won't mean anything? There wasn't even a journey in there to experience the characters going through it, it was just panel after panel of "what's going on?" and then it ends and that just happened.
...At least it ended happily.
