On Line is a movie about a group of ultimately interelated characters that spend a large chunk of their time on the Internet, primarily Internet porn sites. Some of the story lines are weak and the stronger ones aren't completely played out, thus the movie didn't fully grab me. It was fasinating in one respect: I brought viewers into a world that many of them may never be exposed to. While most people will deny it, I would guess that the percentage of adults that spend even a fair amount of time on the Internet have, at one time or another, viewed a porn site. And while most of us probably have only limited experience with this form of adult entertainment, there are many others that are totally engrossed in this world. In fact, many of these people rely on these types of sites for much of their social interaction. On Line takes you into the world of these people and provides a glimsp of what their world might be like. Not a pretty picture.
