You can probably come up with your own list of movies that would be great even if you watched them on a PalmPilot. But I'll bet that running through them is a connection to other people that suspends disbelief. It's not just movies. This same magic is found in great books, music, paintings-you can make a case that it is the definition of art. That's why the Internet is so confusing-and troubling.
Web content is sometimes informative or passably entertaining.
Part of the problem is the anonymity of the web. In real life you could never be as honest or as deceptive as you can be online. The extremes can give cyberlife a soap opera quality. The possibility for pen-pal relationships is neutered by the soundbite quality of writing in chat rooms and electronic communities. Combine these and the open forum becomes a barrier to discovering anything about others, or about yourself through their experiences.
