This is all getting just a little bit too frustrating and repetitive for me now. 'Knocked Up' was only made mildly bearable by the input of funny man Seth Rogen. '27 Dresses' was harmless-but-forgettable to say the least and 'The Ugly Truth' I could handle - only once mind. But 'one trick pony' (and a very unimaginative pony at that) Katherine Heigl has gone five rom-coms too far with the insanely predictable and infuriatingly clichéd 'Life as We Know It'. How many more desperate male leads will the former darling of 'Seattle Grace Hospital' be able to wrangle into playing alongside her, in these identically mind-numbing films?

After a disastrous blind date which was set up by their two best friends - who have only started dating themselves - Holly Berenson (Heigl) and Eric Messer (Duhamel) would be happy to never see each other's airbrushed faces again. But this is film land, and of course the beautiful pair are forced to get along for the sake of their godchild Sophie (the Clagett sisters), after their friends marry and become parents.

However, after a tragic accident, that leaves their beloved goddaughter an orphan, Holly and Messer are faced with the daunting task of taking responsibility for the toddler. How will the two survive, struggling to succeed in their careers, trying not to kill each other and living under the same roof while caring for a baby?

Let's just admit it; we've seen it all before. Heigl is the ditzy, unlucky-in-love singleton, who is as uptight as I was after sitting through this film. The most exasperating thing is that while it's expected from Heigl at this stage, Duhamel seems to have also settled on relying on mindless cushy rom-coms for the rest of his days (a pretty decent actor wasted in my opinion). Who would have thought that the shame of 'When in Rome' - possibly the worst film of 2010 - would send him running right into the arms of yet another chick flick.

After the first 10 minutes, a seven-year-old would be able to effortlessly foresee the outcome - maybe that's why they called it 'Life as We Know It'. Yes, the hour-and-a-half is made up of some amusing moments - Duhamel has a certain charm that can only be admired alongside his astounding physique, and I have to admit that he and Heigl are a winning coupling for this kind of film - but the cons outweigh the pros, as the plot regurgitates so many outdated gags you would almost swear it was a mischievous spoof of the genre (which would actually make it way more bearable).

If it's a 'Raising Helen'/'Cheaper by the Dozen' type movie you're after, then this will be right up your alley. If not, then now might be a good time to pull a good old sickie or don't say we didn't warn you.
