The experience of motherhood and friendship is examined in “Babes.” It’s not a serious study of the complexity of such a relationship, but mostly a goofy comedy co-scripted and co-starring Ilana Glazer, who works very hard (with collaborator Josh Rabinowitz) to keep the material at arm’s length from a more sincere take on the journey of pregnancy. Actress Pamela Adlon (perhaps best known as the voice of Bobby on “King of the Hill”) makes her feature-length directorial debut with the endeavor, and while she gives the movie a little jazzy pixie dust during its opening act, she soon submits to the tired approach of modern comedies, filling the effort with lengthy improvisational duels and lame ideas for silliness. “Babes” eventually succumbs to formula, and while the picture begins with some mischief and insight into the fogged mind of post-partum frustrations, it ultimately becomes a weak Judd Apatow-style viewing experience.
