It's pretty normal here.In fact it's a lot more comfortable watching a movie at the cinema here in Qatar than lets say in India.I have seen Casino Royale in India for the first time with a friend and a lot of people in the hall started screaming and yelling as soon as Daniel Craig first appears on screen!.They were like "Daniel Craig! Daniel Craig!".Not to mention the constant cheering and swearing at various scenes throughout the film!
Of course,with all due respect to all Indians.
