Boring watch, won't watch again, and can't recommend.
Paul Rudd (especially) and Jack Nicholson are actors I would use as a barometer for movie quality, and even Reese Witherspoon (even though I'm not a big fan) usually is in quality movies, but this is just such a dud.
It's the rom com equivalent to watching paint dry. Everything about it draws enormous attention to what you would expect to be happening and not doing it. Trust me, I understand that subversion of expectation is comedy, but there is a rate of diminishing returns on the repetition and duration of the joke, and if you play with that line, then you're writing a comedy for comedy writers because they are the only ones that are going to look at the movie / life as a punch...
