I love this movie I saw this movie around 1980ish when I was 18. Yeah it gave me a lot to think about, which is the whole point.
For all of the people saying that kids shouldn't watch this, I have to wonder why this is so bad and so many of the other horrible things in the media are okay? If you're not a believer I totally get it, but if you're a Christian, this is what the bible says will happen.
Sure, the acting isn't the greatest, but I love movies like this. They weren't really meant to be blockbuster hits, their intent is to get the gospel message across to people. As Christians, this is the purpose.
There are also a couple of sequels: "A Distant Thunder" is also one of my favorites.
