I don’t like the cinema very much myself,but my friends they all love it,and so I often find myself sitting in the dark trying to follow through the conversation on the screen while sweet papers and crips packets are being opened enthusistically all around me. it is this sort of annoying disturbance at the cinema,which it means that I would rather prefer to get a video and watch it at home .Then there is no risk of getting cross because it’s impossible to hear anything what is going on.Another problem is that I always do my own best to find a seat with a good views of the screen during the advertisements. Then,at two minutes before the main film is due to begin,the seat in front of me will be taken by a heavy weight boxer who blocks out most of the screen and so ,by this time,it’s too late to move.I know this isn’t really the point.
