Nope, fall asleep yes (Sphere), but I couldnt walk out.
And to the original post, when we went to see We Are What We Are, we were the only two in the cinema. And we enjoyed it, and having the small screen to ourself. (A perfect example of why there's smaller screens and more of them now, can't always have sold out cinema screens)
I was in a sold out screening of 'Buried' and some guys down in front of us played games on their mobiles all the way through.
This is why i like front and centre seating, so I dont have the rest of the audience bugging the B-Jesus outta me.
For Be Kind Rewind, I wanted it to end, but I couldnt walk out or fall asleep, or let on I didnt like it at least a little bit cause I didnt buy the ticket.
