DVD: Jeff, Who Lives at Home (15)

“Do you know anything about adult relationships?” yells obnoxious Pat (Ed Helms) at his spaced-out brother, Jeff (Jason Segel), a 30-year-old man-child who spends most of his time smoking weed and re-watching the M Night Shyamalan movie Signs in his mother's basement.

When an addled Jeff gets a call from someone asking for “Kevin”, he's convinced it's a “sign” and pursues various “leads” around Baton Rouge. This low-key comedy from the Duplass brothers (the kings of mumblecore) is droll and quite touching.
