Nope.. that's not what you said earlier.
This discussion "started" when you said "almost all unique movies have a similar storyline" - which I have quoted in my previous post. Now, that you are making amends to it, saying that only some do - I don't see a need for discussion on that.
Of course the choice to watch a movie or not, lies with the audience. That's not the point of the discussion. If I don't watch Vijay's movies as a fan, that does not mean that I can't discuss the stories that he chooses to act in.
That brings us to the point, it is not solely the director who is to be blamed for the story. It is after listening to hundreds of stories like this, that an actor of Vijay's stature decides whether or not to act in it. Yes, the director usually comes up with a one-line on the story and actors such as Vijay + Dir/Story team contribute to building it, with their inputs usually. That's what's popularly called "Story discussion" in the film circle. It would not be well thought out to say, a director is fully responsible for the story made for an actor of Vijay's calibre.
Which brings us to another thing: If it is the Director/Story ownership route that we are taking (that is actor has nothing to do with it) why did Vijay decline to play the role that Cheran played in Autograph? Since it went on to become a block buster, Vijay had mentioned in several interviews that it was a huge error on his part to have missed the role, when Cheran offered it to him.
