When we saw the last James Bond film, behind us sat a mum with three children, they kicked my seat all the way through, fidgeting all the time, talked, and as the film got to crucial points and the music became very loud and dramatic they took that opportunity to shout loudly to one another.
I turned around several times but the mum (who wasn't sat directly behind me) looked studiously ahead.
I was incandescent, and by the end I felt the film has been ruined for us, my husband uses a walking stick, so moving was in my view out of the question, I felt it would have disrupted the film for everyone as we were near the front, and the cinema was fairly full.
When we left the film I called for the manager, who was very very apologetic, I pointed out the family, expecting him to speak to them but he did not. He said they usually send someone in to each film showing - just to check, but they hadn't done it for ours, but his suggestion was NOT to move, but to leave and fetch a member of staff.
We did have 4 free tickets, but haven't been back since.
I feel cinemas need to really explain clearly the etiquette that needs to be followed, so everyone gets to enjoy the experience. Like others have commented, you do not sit munching n slurping your way through a film at home, (do you?) that started to interfere with the enjoyment of the film 10 years or more ago, now it's phones (which I have just heard some cinema chains are thinking of allowing!), chatting AND eating n drinking. I dread to think what's next!
