Well, that is fine. For you. But other writers might feel differently.
There's being critical of something and then there's beating a horse to death trying to sway the opinion of others.
Whatever issues some have with the movie, it's done and there's no changing it and saying that nine out of ten people are wrong for not seeing issues with the writing just reeks of sour grapes. Especially when no one can really define what "good writing" is. We get vague allusions to people who are having "conversations".
