Vicky Wight’s “Happiness for Beginners” asks a question that it answers with more authority than just about any other film I’ve ever seen: Can something still be considered a Hallmark movie if it was made by Netflix? Legally, not so much. In every other sense, however, there’s no longer even a shred of doubt. A flat and glossy film about a newly divorced woman who decides to walk the pain away on the Appalachian Trail (a two-week excursion that finds her tripping over tree trunks and falling for a hunky ex-doctor who looks like the human manifestation of a Home Depot), this veritable “Eat, Pray, Hike” leaves no trace of originality or dramatic consequence.
