Ten years ago, Lauren (Lauren Ann Miller) and Katie (Ari Graynor) met through their mutual gay BFF Jesse (Justin Long) at a party. Once the credits finally roll on this wannabe rom-com, you'll wish they hadn’t.

The story goes like this. On that fateful night an inebriated Katie took a lift home from straight-laced Lauren and decided to pee in an empty drinks cup, as you do. Cue a speed bump and said pee spilling all over Lauren (obvious much?). From that moment on the girls became sworn enemies.

Fast forward 10 years and Lauren has been dumped by her po-faced boyfriend so that he can go and find himself for a summer in Italy. He's kicked her out of their apartment, while would-be writer Katie's rent has been bumped up to a rate she can't afford. Lo and behold, their BFF Jesse intervenes and soon the girls are living together.

It’s not long before Lauren discovers that Katie works part-time as a phone-sex operator – a series of scenes filled with over-the-top moaning and dirty talk gives the game away. Lauren, who has conveniently just lost her job and is in desperate need of earning some cash, convinces her potty-mouthed housemate to set up her sex-line independently so she can make all the money with Lauren as her billing department. And yes, you guessed it; it’s not long before Lauren wants in on the action.

From here on in the jokes should really write themselves, but they don’t. Instead they are limp, lacklustre and certainly not laugh-a-minute. To try and compensate for the non-humour there are some cameos from Seth Rogen, Ken Marino and Kevin Smith, who play callers to the girls’ sex line. However, as the men-folk try to live out their wildest fantasies with the girls, it feels decisively more awkward than amusing.

With not much of a plot, For A Good Time, Call... is trying to rely on its comedy and sassiness to pull the audience through. It fails in both these departments. Neither Miller nor Graynor is strong enough for the leading-lady role (although Graynor is the better of the two), and the story is certainly not worthy of a rom-com tag. Yes, it has some of the ingredients of the rom-com formula - friendship, heartbreak, romance – but in this instance, they are all past their sell-by-date.
