On Demand movie highlights

Raising Helen ½

(Encore on Comcast) Hard to hate, but you may be tempted to try. A tale of a spoiled Manhattan princess (Kate Hudson) who inherits her sister’s three children and becomes a better person through motherhood, Garry Marshall’s film boils down every feel-good cliche of the last 15 years into a lumpy mass of multiplex comfort food. Featuring John Corbett, the decaf-latte himbo of “My Big Fat Greek Wedding,” as a love interest, and Joan Cusack, whose talents are wasted. (PG-13; runs through May 1)

Ty Burr

Crash ½

(Showtime on Comcast) Million Dollar Baby” screenwriter Paul Haggis delivers for his first film as director one of those Terribly Important something-is-rotten-in-LA barn burners that grabs you by the lapels and tries to shake you up. The result has some fine individual scenes and a lot of forced irony; Haggis’s past as a TV writer shows. Don Cheadle, Matt Dillon, Ludacris, and Thandie Newton stand out in the large, milling cast. (R; runs through May 20)

Ty Burr

Thor ½

(Comcast Movie Collections: Just In) Do we really need a big-screen ‘‘Thor’’? Not as much as Marvel Comics does. This is diverting enough, with Chris Hemsworth an acceptable Dude of Thunder and Natalie Portman going amusingly gaga as a plucky astrophysicist. With Anthony Hopkins, as Odin, and unimpressive 3-D effects. (PG-13; runs through May 25)
