There are two Bob Trevinos in “Bob Trevino Likes It.” One of them makes Marianne Jean-Baptiste’s character in “Hard Truths” look like parent of the year. The other starts out as a stranger, and grows into found family.

The movie, written and directed by Tracie Laymon and based on her own experiences, centers on Lily Trevino (Barbie Ferreira), a lonely 20-something in Kentucky who friends Bob on Facebook. She was hoping to connect with her father (French Stewart), a deadbeat recently gone AWOL. Instead, she and Bob the introvert (John Leguizamo) develop a tender intergenerational bond.

Setting aside the datedness of the technology — Lily often posts 2010s-era Facebook statuses littered with hashtags — “Bob Trevino Likes It” is a middling indie tear-jerker. It suffers from an overwritten script chock-full of tropes and artificial dialogue. “You don’t have any tools,” Bob exclaims to Lily at one point, meaning a literal toolbox, but also, you know, a metaphorical, emotional one.

Any genuine feeling emanates from Lily. Ferreira pitches herself into the trite story line with enthusiasm, and her verve breathes life into even the most leaden lines. On a handful of occasions, Laymon has her protagonist gaze into the camera in shallow focus with a swirling effect around her head. The moments viscerally convey a feeling of belonging by making use of a considerable asset: Ferreira’s wide open face.
