PLAY SENRAN KA-nah, can't make that joke. On to the question, do you prefer when a fictional work has got an open ending that pretty much makes sense but leaves some things hanging or a bad ending that brings definite closure but kills off your favourite character?

The former, I was never a fan of bringing closure to a story/character that involves killing said character off. I suppose it doesn't matter that much if the story isn't that good in the first place (on the principle of not being that invested in it the first place), but if the characterization is good, then it matters, and I personally prefer a character seeing trough the day with all the experience he/she gets than getting that experience and then die at the end. Not saying killing off the character necessarily nullifies what the plot has been doing up to that point, but "drama by death" rarely is my cup of tea.
