I liked the poster and I am very mixed on the trailer. It really looks like it is a "Hangover" with women. Do women need to prove that we can fart and burp just as well as men? But I am still not convinced it will suck. Maybe the whole thing turns out to skewer the wedding industrial complex. Now that's something I would be interested in seeing.
But I am going to watch this one a bit carefully because it is a comedy, written by women and starring women and we need more of them badly.
