Talisker

Personally I watch anime as an escape from the real world. I deal with enough "sad" things in my life. So I prefer the happier endings or funny ones in anime, in all my escapism media for that matter (books, games, etc).

I mean, I can respect a well done sad ending. Though I prefer it be a little open ended. so that even if it is upsetting you can kind of make your own ideas, judgments, or even assumptions on what happened after the credits roll.
