It's not a blanket rule, obviously. I've seen your numerous pans in the review section of this site to know that it is not a blanket rule for you eitherQuoting Irish (view post)
I watched 300 at the theater. I've never walked out of a film for non-technical reasons. I will also tend to watch all of the way through films from well-known directors for completionist purposes (1941 is a good example of that). And I'll keep watching and not be a dick about it if it appears that my wife is liking it.
