I would say online reactions can be just as passionate and intense as those given by live people.
Uh no, I just cannot agree.
Last night I sat with a group of 80 people in a small room watching two B mysteries - a Whistler and a Mr Moto.
No "internet experience" compares to the audience hush as the movie starts, the gasps, the laughter, even the silence in the tense parts. Half the fun of watching movies, is watching them TOGETHER, it very much elevates what would be a so-so or even boring movie watched at home on a computer.
During the intermission, everyone was smiling, talking about the first movie. It's a communal, shared experience. Many linger at the end of the night to discuss their opinions. It's just fun really being together, interacting with real people.
I feel very sorry for generations of people growing up not realizing what social skills & joys are lost because of the "instant" and "singular, self-centered" world of the internet offerings.
