We know it's super early pre-alpha footage, we are not bitching, we are worried because the trailer alone, and still some of us think the trailer looks bad. That's a fact.
I'm not sure exactly what you are saying here, but if you saying that the trailer looks bad and that is a fact, then you don't know the difference between a fact and an opinion. And it's hard to take your opinion seriously if you indeed don't know that distinction.
The fact is that some people will enjoy this teaser and some will not. And my opinion is that it doesn't matter much.
My reasoning that even a shitty trailer (which this is not) would be better than nothing at all is because the media is already posting stories about it, and are pointing to the fact that the Kickstarter is in its final days. This is the point of releasing this days before the end - to remind people to pledge, to remind people that this campaign is in its final hours. And it's working because funding has gone up well over 50k since last night.
