Veronica Mars: The Complete Second Season: Season 2 matches Season 1 for the complicated ingenuity of the murder plot, which starts with a bus going over a cliff. Everyone from a janitor to the mayor is implicated. Teen detective Veronica (Kristen Bell), cynical in a twinkling way, sorts it out. Extras include a gag reel.
Rome: Season 1 of the HBO epic, ending in Caesar's assassination, boasts performances of power and subtlety (especially Lindsay Duncan as the cunning Servilia) and startling, even kinky, details of life in the empire. Extras include historical commentary.
