This guy spent his life savings on the trailer.

Taking risks is one thing. Jumping from the Empire State Building without a parachute is another. I think this man can start saving again, because he - clearly - hasn't found the duck with the golden eggs. I mean he has found the duck. But the eggs are bad.

The concept of angels and demons is not that original to come up with. I have been thinking about this concept for several years now myself. What you need is a good angle to bring this subject. Chasing for dragons is not a good angle. The only right thing he has done is touch the rivalty between good and evil. But that's an obvious decision to make. You didn't even needed to think about that. I don't want C-grade special effects, B-list actors and an expensive A-list production crew. I want a good angle to bring this damn concept. Cheesy dialogue, the most obvious sound effects, the most unsubtle music since Alexander and wooden acting add nothing further. I mean, what can seperate your story from the mythological tv-stuff like Xena, Hercules, Earthsea, .. etc. What's your cinematic IDEA??

This man makes a short film of five minutes and he can't hide (already) what his interests are with this material: special effects extravaganza. Instead of so many people working on this trailer or short film, whatever you want to call it, all he needed was one script editor to tell him he had nothing to start with (yet). Sorried to say that, but it's true. Some Hollywood producers have made this kind of special effects-garbadge into films already, but that doesn't give me reason to give this guy a chance.
