I haven't seen it yet, but I have heard that while it may have some good arguments, it also has some really poor ones that are too speculative and thus far less credible, which makes the whole movie easier to dismiss.

I saw and agreed with most of what was mentioned in that documentary.

I first watched it about 2 years ago. I liked it and it made lots of sense but some claim it is not really accurate. OK. Accurate according to what?

I ain’t got no none need for no video for me to say I ain’t got none belief in no JC.

While I was already an atheist when I watched it, it did provide a bit more background on myths I wasn't as familiar with. Made it easier to point out the glaring similarities between the religions, minor or major, and describe how they explain natural phenomena. Doesn't seem to sway the devout, though. They see it as the devil.
