THE DEPARTED ***½ (Comcast Movies: All Movies) A relentlessly violent, breathtakingly assured piece of mean-streets filmmaking, and damned close to the Great Boston Movie. Martin Scorsese returns to form with this complicated cops-and-Irish mafia saga (based on a 2002 Hong Kong action flick); Leonardo DiCaprio, Matt Damon, and Mark Wahlberg all do quality work, but Jack Nicholson steals the film as, essentially, Whitey Bulger’s evil twin. Local boy William Monahan scripted. (R; runs through Aug. 31) TY BURR
I LOVE YOU, BETH COOPER ** (HBO on Comcast) Writer Larry Doyle (“The Simpsons’’) adapts his novel about a high school geek (Paul Rust) enduring one long night with his cheerleader dream girl (Hayden Panettiere of “Heroes’’). Chris Columbus directs, and what could have been a nice John Hughes revamp ends up just another teen stu-com. (PG-13; runs through July 18) TY BURR
