Other people have already pointed out most of the things that I would have said, so I'll just add in one more point: the posts you're citing aren't particularly recent, and the people who wrote them were themselves citing older versions of the script. What are BTB and Synchysi supposed to do with complaints that are both unfocused and outdated? Of course it shouldn't be impossible to give useful criticism of the script (eg. I think that lines ABC aren't very good, this is why, here are a couple ideas of what they could be changed to) but I can't recall the last time someone actually tried to do that.
