No more and no less than a solid middling comedy.
In the age of the coming-of-age comedy, nothing is more prevalent than indie music montages and sad sap protagonists with remarkably expensive looking hipster clothing. Thankfully, Adult Beginners really has neither of these characteristics. The characters in Adult Beginners are past the point of coming-of-age, and therein lies the point. It may be formulaic and glossy in its ultra quick stereotypical depictions of IPOs, swim classes, successful entrepreneurs, awkward home town reunions, etc., but judging the film on these miscues is to miss the (aforementioned) point. What Adult Beginners does well is allow its very talented cast to execute a cute story featuring very familiar circumstances and themes.
