Pretty lame. Good cast is pretty much wasted. Katherine Heigl is quite brittle and you can guess her little secret early on. Amanda Seyfried is underused. Diane Keaton is virtually the same mother character she always plays. I hated Robert DeNiro's character - was a sleazy old creep. Susan Sarandan, not at her most likeable either.
I also didn't like the stone-faced biological mother - very cliched until the very end.
Plot is wafer thin. Can't even be bothered repeating it, and it seemed most of the "adult" cast were, or had been, involved in some shocking sexual thing. The younger cast are pretty tame by comparison. The bit with the "moms" at the end was a step too far for disbelief.
The whole thing had me rolling my eyes, and Robin Williams as some marriage advising vicar thing again - didn't he already play that role in that godawful Mandy Moore movie from a few years back? It's not much better here.
There are a few tame laughs, and it is good to see Topher Grace onscreen, but most of these actors have made far better movies in this genre. 27 dresses, Because I said so, Win a date with Tad Hamilton, Mean girls. Rent one of those instead!

Could not even pretend to sit through this one. Was bored within two minutes.
In all fairness, I do hate westerns and action films to start with.

Actually downgraded this - was worse than I remembered. The three leads are great and I liked the idea of the downtrodden office workers, but it goes too heavily into the revenge and becomes boring. I also hated the three revenge fantasies. Too long and pointless.

Not bad. Dragged a little in places, but fine as something non demanding to have on in the background. Not exactly heavy in plot or hard to follow.
