Where did it all go wrong?
I'd say at the point you wrote "don't...tell me what I...should not watch."
Star Traveler had not told anyone not to watch. Basically he informed about the movie's bad reviews and it's lack of biblical fidelity.
There's the barest possibility that could be called "preaching"...
Ummmmmm, what? This is from your homeboy who didn't even watch the movie........LOL!
