Here, the fart jokes are carried out with the intricacy of a professional blueprint, and they fall flat. It's just insipid. When an entire fart joke is set up so that one of the Klumps can get the Heimlich maneuver, fart and ignite a fire from the flame on a birthday cake, you know that Murphy and his cohorts here are trying far too hard. There are also dick jokes, tit jokes, piss jokes, shit jokes, and vomit jokes. This is really base, really lowbrow humor.
Trouble is, it's been done so much better by so many other folks lately.
We expect a lot from lowbrow humor nowadays. This isn't funny, it's nauseating. She is cute and sweet and as innocent looking as hell, so she almost evokes some emotion from the audience. Part of the problem surely lies with director Peter Segal. He is way out of his league here.
