I've watched this also. If you understand the why of the enemies "behind the scenes", you'll be surprised how many deceptions in society (and apostasy in churches) start to pop out at you! If we are to test all things, and expose the lies of the enemy, so we can warn others not to be deceived, the information in this documentary is VERY helpful!
When planting seeds for Christ, make sure to till the soil with God's Law first. Then, make sure to plant intact, whole seeds, and not ones that have been chewed up and spit out, and will not grow.
