Too much narcasism
It's so overly dramatic it presents itself as the greatest movie ever, yet there was little actual animation. It's rediciously easy to make fading text, which was the majority of the trailer. Read that text outloud to yourself and try not to laugh-- it'll probably leave before you can finish reading it, anyway. Plus the one photograph of the city that was rendered as a vector drawing, I just hate it when people do that. Nobody had any shadows, plus the sound quality was poor.
