OK, so after reading the other comments I was expecting the film to be dire. But it was, in fact, quite funny. I laughed out loud in some places and I'm sorry if you folks don't find the fact that pregnant women fart or that old guys have dangly balls funny but I'm not too high brow myself and I actually liked this film a lot. It held my attention, and I was in fact still smiling as the credits rolled.
I'd happily recommend it to anyone who wants a bit of fun without the nastiness and drama that lots of films (even comedies) feel obliged to dole out.
So why not give it a chance?
