Don’t Think Twice (B+) is light and dry like the last warm day of autumn, and an assured effort from writer/director Mike Birbiglia. Gillian Jacobs is a marvel. For a movie about improv comedy, it’s more bittersweet and nostalgic than consistently laugh-out-loud funny, though there are plenty of lived-in moments that show the deep history and affection among the troupe as they struggle to deal with jealousy, resentment, and personal disappointment of the ascent of one above the rest.
