Yes, it has stupid boy humour but it’s also surprisingly mature too. I particularly am guilty of over-planning my life. This whole movie deals with how to cope with unplanned events. It’s not just logistical issues that’s difficult, it’s the lower approval rating of friends, family and colleagues that’s difficult as well. I found it pretty realistic, especially in the hospital when Allison is fighting with the doctor about procedures. How many movies show that? Anyways, it’s actually worth watching but it might be too sappy for those hoping for only stupid boy humour.
