Some people are funny in that they (sadly) take perverse satisfaction/joy in looking to find fault with or diminish things that should be embraced with enthusiasm.
Anyone who has had the honor&pleasure of reading (and truly appreciating) Moore & Gibbons superlative, epic, groundbreaking maxi-series/graphic novel should rightfully be elated by the WATCHMEN teaser trailer. Could any of us have hoped in our wildest imaginings that there was even a chance of this "hallowed" work being cinematically rendered as faithfully as it now appears to be the case? I am astonished by and grateful for Mr. Snyder's obvious reverence for the source material.
Would that motion picture executives were wise enough to ensure that all adaptations of beloved works were placed in the loving, caring, capable hands of filmmakers who were dedicated to TRANSLATING a work from one medium to another rather than embellishing or altering it.
To sum up: all of you miserable bastards who (would) gleefully look to s(p)oil this triumphant first glimpse of what - against all odds - appears to be a worthy adaptation of one of the most celebrated works in the annals of illustrated fiction / graphic literature really need to submit to a little self-examinaton in order to gain some insight into just what it is that accounts for your tragically toxic 'tude.
You can call me by the derisively-intended label of "fanboy" if you will/must, though it's an ill-fitting stereotype of a term that has by this point been so overused as to do no more than to mock the person who attempts to use it as a supposed insult.
