Re: Better if they had allowed main cast to die?
Why trash something nobody will debate you about when you can trash something that will generate some discussion instead?
I suspect some of it is just posters playing devil's advocate against a popular viewpoint. Once in a while there might be a valid point presented, but usually the posts seem designed just to push people's buttons. Especially when there are topic titles like "Don't you think [Actor/Producer/Character/Episode/Series/Film/Obscure Line of Dialogue] was the worst thing about Star Trek?"
