People always have a way of showing themselves to be horrible, I guess.
A lot of ideas and thoughts and outlines are done during a creative process that will never make it to the final product. It's not a slight against anyone if people ran out of time or they decided in the end it didn't fit a character. It's just something that was never done, a half-finished idea that never took anything away from anyone.
I really wish more people understood how this works, because it's really a shitty thing to react in such a nasty way to people who did a damn good job delivering four years of their life in a neat little package for everyone to enjoy. And what happens? People spend more time crying and whining and complaining over things that aren't there than enjoying what there is. It's disheartening to say the least.
