It doesn't matter that the raunchy comedy Rough Night was directed by a woman. It also doesn't matter that Rough Night employs a group of talented actresses that includes the fiercely funny Kate McKinnon.
And while we're on the subject of irrelevance, you should know that it's equally unimportant that Rough Night gives us a much-needed opportunity not take Scarlett Johansson seriously or that the movie makes no fuss about a gay theme with Zoe Kravitz and Ilana Glazer playing former lovers.
Similarly, Jillian Bell's portrayal of the gal pal who Johansson's character has outgrown since the two bonded during dissolute college days is of little consequence.
It doesn't even matter that the movie follows a well-tested formula for crass comedies.
All of these things could have made a difference had this comedy about former college classmates who gather for a bachelorette party in Miami been either perceptive or funny. Maybe, Rough Night isn't funny precisely because of its inability to get close to anything that might be called incisive.
An attempt to darken the comedy -- the women accidentally kill a man they believe to be a male stripper -- isn't handled with enough wit or finesse to save the day. No Weekend at Bernie's, Rough Night arrives on screen as a painful misfire.
Any movie that resorts to cocaine snorting for one of its running gags -- as this one does -- immediately declares itself ineligible for any awards involving imagination.
Even the brilliant McKinnon, who plays an Australian visitor to the US, can't hit the necessary high notes, and the movie leaves us wondering what motivated the filmmakers to encourage McKinnon to channel her inner Naomi Watts.
Although designed as an ensemble comedy, the movie revolves around Johansson's Jess, a woman who has left her hard-partying college days behind to run for the state Senate. Once in Miami, Jess quickly sheds her sense of propriety to join what's supposed to be a fun weekend of clubbing hopping and debauchery.
Now and again, the movie offers scenes involving Jess's fiancé (Paul W. Downs). While the women are trying to be wild in Florida, Downs's character attends a sedate bachelor party. He and his buddies spend an evening at home in New York testing wines. Attendees include comedians Eric Andre, Hasan Minhaj and Bo Burnham, all mostly wasted.
Director Lucia Aniello doesn't do much to explore this bit of role reversal, and Downs's character quickly heads to Miami on a non-stop car trip involving adult diapers, stimulants and beer. Why adult diapers? So there's no need for him to make bathroom stops. A misunderstanding leads Jess's fiancé to believe his impending marriage may be endangered.
In Florida, the women stay at the upscale home of one of Jess's major donors. They also meet a couple of leering swingers played by Demi Moore and Ty Burrell.
Low on creativity, Rough Night at one point finds McKinnon's character feigning sex with the corpse that the women desperately are trying to hide. So, yes, this one tries everything, including a joke about necrophilia. Like the corpse, the joke dies. The movie isn't far behind.
