Awful. From concept to execution this is one of the most irritating and hollow movies I have seen. The characters are mostly insubstantial with the exception of their petty, idiotic, selfish, and cruel traits. Josh might be the most hateable character I have ever seen and the idea that one woman would marry him while another woman would love him from afar is frankly insane.
The conceit of the movie that marriage is supposedly awful for the first year is preposterous in a society where nearly everyone chooses their spouse freely. The movie has nothing useful to say and the humour is unrelentingly sardonic in the worst way. Save yourself a couple hours and skip this one.
