For one thing, just getting to the theater presents difficulties. Leaving a home equipped with a TV and a video recorder isn't an attractive idea on a humid cold, or rainy night. Even if the weather cooperated, there is still a thirty- minute drive to the theater down a congested highway, followed by the hassle of looking for a parking space. And then there are the lines. After hooking yourself to the end of a human chain, you worry about whether there will be enough tickets, whether you will get seats together, and whether many people will sneak into the line ahead of you.
