Hannah Marks and Joey Power's "After Everything" was the best film to play in competition at this year's SXSW film festival. It represents a strong debut by the filmmaking duo because it agreeably understands, and never judges, the cash-strapped, NYC-based, millennial couple at the center of its tangled love story. The film is both idealistic and shrewdly cynical; it never necessarily sets for a settled mood because, well, that's now how life works. And yet, for a film dealing with such heavy themes, it manages to be curiously humorful.
