Is it better when you pay?

I do often wonder if I rate movies higher when I see them in the cinema. There have been so many occasions where I’ve been in a cinema watching the end credits,  trying to gather my belongings while brushing off popcorn and I’m already planning the review and score in my head. I start to discuss the film with my buddy/buddies and it’s almost like a group hysteria we’re all generally hyper about the film. On the odd occasion we’re all bummed out about it. I’m not 110% sure on the social psychologies involved, it’s possible that there are group laws working between us, maybe if a group of 6 are positive about a movie then the 7th person will just fall in line??
