Rebel Wilson is the only one you can really like here, but her screen time is less than the other three.
Maybe I just expected better because of the cast. I will have to watch it again sometime with my lowered expectations.
Actually did appreciate this more on a second viewing. Realising it wasn't going to be a laugh a minute (though there certainly are some dark laughs to be had), I could better see these girls are actually quite troubled. I didn't find Isla's character funny this time, actually she's very sad. Funnily enough, I liked Kirsten more this time.
A flawed, but decent study of the rivalries hidden behind friendships.
Better off watching Bridesmaids instead.
