Good Marketing VS Good Story

Let's face it, there's definitely a chance that the people entrusted with Prometheus are better at viral marketing than telling a complete story. So far, I think the marketing has been great, except that it gave away too much. Does this marketing over-promise? Maybe. Should we blame them if it does? Of course! But, if they deliver on their promise, then kudos to them! I'll have an honest reaction either way. If people get ticked off because they feel they got duped, it wouldn't be anything new, that sort of thing has been going on forever.
