This is getting a lot of flack because people are comparing it to Bridesmaids - it is a different movie. Several people are saying the characters have no depth, which is true, but anyone who was in a clique in High School, graduated circa 1999 would understand the idea of the first wedding in the group. It is relatable in that sense.
It is a movie that will entertain for the duration and cause a couple of laughs in the process - what more is expected from a movie?!!
