Play the Summer Movie Challenge! In following up smash hit “Borat,” Sacha Baron Cohen is back to push all of the buttons while impersonating gay Austrian reporter “Bruno” – race, nudity, sexuality (even fashion). And the reviewers like it, giving it at press time an impressive 80% rating at Rotten Tomatoes. While Variety bemoaned a “pronounced nasty streak,” Emanuel Levy called Cohen’s latest “wilder and risker” than “Borat.” JoBlo.com called it “sick and offensive but pretty damn hilarious.” Did you expect subtlety?
