The weekend before we had our baby we watched the film "Knocked up", a kind of irony of sorts (we didn't know he was actually going to turn up the day after).
But what we thought was a comedy turned out to be something with a little bit more substance than 'just a comedy'. Apart from being very "close to target" on the actual subject, it was also a little bit deeper and a little bit more daring than either of us expected. The only thing I didn't particularly like was the way they portrayed the male lead's life. It was just a little out there for my taste.
I warmly recommend it, perhaps for anyone who wants to feel good about their own relationship and for anyone who just want to have a few laughs, and definitely for anyone close to the subject of expecting babies. :-)
