To claim that Jesus Christ did not even exist is mere ignorance. Such preposterous claims belie a desire for some illusion of moral or intellectual superiority. The argument is nothing but a straw man easily knocked down. There is plenty of historical and archaeological evidence to support the FACT that Jesus Christ did in fact exist. The Jesus movie is a good introduction to his life and teachings but by no means comprehensive (for that you need the Bible).
If you're sincere in your search for the Truth, I highly recommend reading Josh McDowell's book, More Than a Carpenter, as an easy first read. Available at Amazon.com, of course.
It's reasonable to question Jesus' deity if you've only heard the name and never seriously investigated His life. Those who have, including the hard-nosed skeptics who set out to debunk this thing called Christianity, often become Christians themselves. Those who don't generally do so out of mere pride -- an unwillingness to sacrifice their old, comfortable beliefs that allow them to live an ungodly lifestyle. But you reject Jesus at your own peril. It's the very height of folly.
As for my opinion of the Jesus the movie? Why not judge for yourself! You can watch the entire movie streamed online at jesusfilm.org in any of 62 languages (of the 858 it's been translated into)! Then you can decide whether or not to purchase the DVD.
I do recommend this film. I also recommend, highly, 2003's The Gospel of John. It is extremely faithful to the New Testament book of John and really brings life and a better understanding to the life, times, and teachings of Jesus Christ, God in the flesh.
I wish you well and pray that God may draw you to Him (that you may be receptive to His call). Perhaps I'll see you in heaven someday. If you have honest seeking questions, you're welcome to e-mail me at robvh at wellness5.com.
