In my opinion, although Lain appears blasphemous on the surface, it is not. The reference to God is allegorical. [spoiler="The reason why. (most of my post is in here, mild spoiler)"]The show predicts and depicts a god that has been fabricated. This god is unable to offer what the God of our faith can. I liked this allegory because it showed that false gods are shallow and empty. In addition to this, the false god was based within the Internet(The Wired). In Genesis we hear about the Tower of Babel, and I think you wouldd agree that in the past century or so we have really been driving the nails into that coffin, especially with the internet breaking down communication barriers.[/spoiler]
The main message I got from the show was the suggestion that man may have created a false god when he created the internet. Interesting pondering material. Here is a good quote:
"If I can operate Google, I can find anything... Google, combined with Wi-Fi, is a little bit like God. God is wireless, God is everywhere and God sees and knows everything. Throughout history, people connected to God without wires. Now, for many questions in the world, you ask Google, and increasingly, you can do it without wires, too." - Alan Cohen, V.P. of Airespace, a new Wi-Fi provider, New York Times, 6/29/03
This is a quote that I think in the years to come, will become quite famous. I'm not saying it's right, i'm saying it makes you think. It pretty much sums up the message I got from Lain. Christians who like thinking a lot will probably love this anime. I liked it anyway.
