This is exactly what you'd expect: a formulaic film that recycles a bevy of overused elements into a somewhat coherent whole, thus squandering the potential of its talented leads. The movie isn't completely unfunny; there are a few jokes that got me to smile (mainly due to Carell's acting ), but they were few and far in between. The overarching "marriage becomes lame unless you go on crazy life-threatening adventures" theme is overplayed and stale, and not handled well anyway. This gets two stars thanks to Carell's usual awkward acting (and no thanks to Fey's bland and forgettable performance) as well as for the fact that the movie is at least watchable.
In a sentence:
Carell is decent, Fey melts into the background, the humor mostly falls flat and the story is void of originality. Less accustomed moviegoers will enjoy this, though.
