I don't care what someone thinks about the trailer in terms of quality. People are and should be free to criticize, debate, and talk about their impressions and analysis whether they think it's crappy, mediocre, good, great, whatever. But there is some hot garbage about cultural significance getting thrown around that is basically objectively wrong.
I'll happily concede the point that this film will be as bad as the prequels for the sake of argument because it speaks to the cultural juggernaut that Star Wars is. Even a bad Star Wars film captures as much interest as Obama did during his presidential elections. That's absolutely insane. That doesn't happen solely because of marketing, you can't just 'replicate' that. Battleship and John Carter anyone? How many failed would be action franchises have crumbled despite the immense marketing machine put behind them? Even if you take a relatively successful franchise like Transformers, it can't even hold a candle to Star Wars.
