“Bad Moms” (*** out of four) was a winning comedy about three overworked single moms (Mila Kunis, Kristen Bell, and Kathryn Hahn) who become fed up with all their responsibilities and attempt to have an overdue shot of freedom and fun but one mom (Kunis) is brought into a personal and professional battle with the bitchy head of the P.T.A. (Christina Applegate nicely cast). Not all that much plot per se but has enough laughs and high-spirited performances to make it worthwhile, especially for single moms who will appreciate this even more. Kunis in particular is terrific as usual.
