2) Soon nobody will go to the cinema: people will watch films only at home.
I have another opinion on the matter. First of all, lots of people all around the world like going to the cinema. It is an amazing activity to spend one's time on. You can go to the cinema with your friends and immediately after the movie you can go to a cafe where you can discuss the film. As for me, that's amazing! Nonetheless, more and more people each day are watching movies at their homes. Lots of new browser have been made recently that help people watch the newest blockbuster just with one click of a mouse. Anyway, I can't agree with them. I can sometimes watch movies at home but I like going to the cinema much more mainly because I can change the surrounding environment and relax away from home.
