From its first moments, when a grown son fights with his mother for morning bathroom time and finally resorts to an unsavory solution involving an orange juice pitcher and steady aim, “The Hollars” announces that it intends to be another “quirky” dysfunctional family dramedy in the tradition of the fine 2005 film “Junebug” and its far less gifted but more eager-to-please siblings, “Garden State” and “Little Miss Sunshine.” Written by James Strouse and directed by John Krasinski, who also stars, “The Hollars” falls somewhere in between those last two movies, slipping into insufferable cliches and contrivances one minute, evincing delicate familial interplay and genuine emotion the next. Krasinski plays John Hollar, a graphic artist and expectant young father living in New York, when he’s called back to his unnamed home town by a health emergency involving his parents, Sally and Don (Margo Martindale and Richard Jenkins).
