Jane Fonda and Lily Tomlin defy convention

Opportunities for women who are older than, say, 25, are infamously rare in Hollywood. And what roles that do come along are often demeaning or artistically unsatisfying.

Another way of putting it: Did you see “80 for Brady?” Older women do whacky things. Hilarity ensues. Or not.

Thus, my expectations for “Moving On,” which stars Jane Fonda and Lily Tomlin — who also appeared in “80 for Brady” — were not exactly stratospheric. But low expectations can fool you. So can two experienced stars (the pair also starred in “Grace and Frankie” on Netflix) who have an obvious chemistry together that glosses over many plot weaknesses.
