I guess what'd you call it is a semi-realistic look at a handful of relationship problems, most of which were the result of the male characters' discomfort with accepting adult responsibilities. A failure to "man up" if you will. It was strange, because while I can identify with some of the issues they were going through (there's enough Peter Pan in me for a few Neverlands), I found myself annoyed at how the characters handled them. K. called it "a chick flick for boys" and I think that was probably the intention of the filmmakers. But it also felt to me like they were pandering to the straight female audience at times, like "Look at how sensitive we are! We see how awful and pathetic all those other men who aren't us are!" Still, all of that could have been made to work for me if it had just been more entertaining. A bit of humor for balance.
Despite my criticsms, it's not a bad movie. And I suppose it might be useful in a therapy way for some people. But it certainly isn't a good time.
