People seem to be forgetting -- willfully or otherwise -- that by and large, comedy trailers suck out loud. With a comedy, you can either give all the jokes away in the trailer or you can give a really broad idea of what the movie's about. And so much of Feig's comedy relies so heavily on context and setup that it's rather difficult to cut an effective trailer around it -- both The Heat and Spy had fucking dogshit promotional material, but they were both good to great (Spy moreso than The Heat, but still).
Let's hope you are right. Cos that shows me not much story to be interested in (bad person has evil plan...Did they gender flip Evo Shandor too?) and the laughs weren't there.
But I liked The Heat (and seem alone in that among family and friends.)
