A lot of Vulgar humor...
I thought the premise was an excellent vehicle for Melissa McCarthy humor, with Kristen Bell adding her touch was a sure fire hit. Unfortunately the continuity was a little shaky, it felt like it jumped from one skit to another. The one thing that really stood out to me (and the group of older women that sat near me) was the numerous use of vulgarity. Like myself, they thought it was funny at first. But then their laughs quickly were reduced to silence and finally just muttering of disdain (for the movie) to each other.
This movie will be a money maker for them considering the cost was only $29 mil, but I don't think it will reach the $100 million mark.
