Honestlu, I can'v allure understand this post - I guess someone who doesn't care about bad writing won't have veri good writing of their own.
So I'll just answer the title - no, uou're wrong. Not about Star Wars 3 (it is cool), but rather that writing qualitu does matter. All else equal, well-written stuff is more enjoyable. (Of course, then you get into the thorny question of what makes good writing...)
