OK, I have no idea what your documentary is supposed to be about. The trailer goes in about a half dozen directions.
Is it about the history of arcades? It seems that way early, them shifts tones.
Is it about a guy who restores game? Maybe, but let's jump to shots of Walter Day and Billy Mitchell that don't seem to have much to do with the narrative.
Wait, it's about a guy whose arcade closes... wait, where was the part where we established him as an arcade owner?
Oh, he rises above! He's inspirational! Or something! I guess why he's a heartwarming character is being saved for the film...

Hey, it could be great. You certainly showed you have some footage of some interesting characters and events. But, I'm not being a jerk... I have no idea from the trailer what your doc is supposed to be. A trailer isn't just where you disjointedly drop your best quotes from your interviews. Right now, this looks like a bad King of Kong follow-up.

Best of luck. I'll follow along. Maybe the next things you post will change my snap impression.
