More dirt

The scripted miniseries "Dirty John," starring Connie Britton and Eric Bana, wrapped up this past weekend — but there's still more story to tell. The two-hour documentary "Dirty John, the Dirty Truth" features interviews with John Meehan's family members as well as the detectives who worked to put him in jail.

Leading men

"James Stewart, Robert Mitchum: The Two Faces of America" looks back at the lives of the two actors, 22 years after they both died within a day of each other. Director Gregory Monro, who previously profiled Jerry Lewis, attempts to go beyond the stereotypes associated with both legends and dig deeper into what the two men represented to viewers.

Rites of passage

"The Passage" ticks off a lot of cliches in the network playbook — guilt-ridden hero on the run! Government conspiracy! The apocalypse! Precocious kid that melts your heart! Vampires! — yet somehow it all works, at least well enough to finally stop thinking of star Mark-Paul Gosselaar as that dude from "Saved by the Bell."
