When a couple breakup, the man struggles to get over it while the woman moves into another relationship. It isn't the sex that he misses so much as just the intimacy of the normal day-to-day things she used to do. In order to fill the gap he goes to see a prostitute and pays her to recreate these moments to help plug the emotional gap.
This is a familiar situation – struggling to let go of what you had with an ex and just move on with it in the past but nothing more. Credit then for the film finding at least a reasonably original way of tackling this and showing us how ultimately unfulfilling and damaging staying in this situation is. The way it is delivered is by excess of paying the prostitute to reenact the most mundane or specific of things. Mostly the film manages to be amusing while also striking true about breaking up so that it more or less has that emotional core while being entertaining. I say more or less because it doesn't totally work and both aspects of the film do rather compromise one another so neither is to its full potential. The dialogue does eventually spell it out a bit much for my taste and I think that the comedic device of "large black woman / skinny white guy" was a little bit too obvious to be overlooking for being such, but it still functions well enough.
Performances are solid; Wasser is nice enough, Middleditch is pained while King may well be a cliché but she throws her all into it and makes the comedy work better than it could have done. The film looks good although the edits are a bit frantic at times and perhaps the material is not as strong as it could have been to support the professional look and delivery. It is a nice film with decent laughs and feels, could have been stronger but still works well.
