This isn't a comedy where you say: it breaks new ground, it's exceptional, it's different. But while it doesn't take big risks, and it isn't exceptional, it still made me laugh far more often then I expected to. There are some decent belly laughs, a few groans, and Anniston/Sudeikis have a pretty solid comic timing between the two.
All I can really ask of a film like this is to make me laugh, and this summer has not had many films that really "worked" in the comedy department. Heat was "OK", but the laughs were pretty sparse. And outside of that, I'm struggling to think of any other comedy that just worked.
If you were a fan of "Horrible Bosses", realize this film isn't as good as that film, but there are still some solid laughs.
