With the exception of George Segal, all the actors here were unknown to me. It's clearly a family affair -- there are three Mastersons in the cast, at least two of whom are brothers, while a fourth Masterson is one of the producers, and the leading lady is or was married to one of the brothers. When they all get together at Thanksgiving, let's hope that turkey inspires better jokes.
It's a guy movie, with the usual sources of humour: penises, erections, anal intercourse, homosexuality, vaginas, periods, menopause, old people having sex, young people having sex, plus a quick flash of authentic testicle. In other words, all the terrors visited upon American suburban males, horrors which seemingly can only be kept at bay by poking (whoa!) fingers and fun at penises, erections, etc, etc.
There is an occasional laugh to be had, but there's no sense of when to stop: what might be funny as a one-liner or a simple sight-gag is drained of humour the more attempts are made to squeeze the dregs of a smile out of them.
Everyone is cute, all the leading characters and pretty much all the support is white. It all seems spookily prescient now we know who these characters elected in 2016.
