The new film of Beyonce and Ali Larter “Obsessed” opened in theaters with bad reviews, but it ranked #1 at the weekend’s box office.

In the film, Beyonce plays the wife of a man, who has a secretary (portrayed by Ali Larter) who is obessed with him. According to critics from RottenTomatoes.com, Obsessed is “a trashy, empty calorie thriller” and “horrifically written and terribly overacted.” At the premiere, Beyonce was then criticized for her black sequined dress with a horrific train.

However, the insults did turn into compliments when the movie dominated the domestic box office weekend with $28.5 million, beating “Fighting,” “The Soloist,” “17 Again,” “State of Play” and “Earth.”

The PG 13 “Obsessed,” which was helmed by tyro feature director Steve Shill, drew audiences comprised 58% of females, with 51% of patrons age 25 or older.

According to Sony’s distribution president Rory Bruer, “This is extremely satisfying,. It had a lot of things going for it, including another great job of marketing by Screen Gems. But most importantly, it had Beyonce and a great cast.”

Apparently, “Obsessed” was produced only for an estimated $20 million. Its debut was the second biggest for Screen Gems, beating the 2006 vampire flick “Underworld: Evolution” ($26.9 million) and the 2005 horror film “The Exorcism of Emily Rose” ($30 million.)
