How Long Do You Usually Go When Watching A Boring Movie, Before Finally Turning It Off ??

I virtually never quit on a movie. I haven't since that episode of Are You Afraid of the Dark when the babysitter gets the kid to read books and he hates it but the book comes to life with witches and ghosts and the only way to stop them is to finish the book. Babysitter warned once you start a book you really should finish it, so I applied that to movies.
