Actress Keira Knightley has sided with movie critics who savaged her breakthrough screen performance - branding her acting "rubbish". The Pirates Of The Caribbean beauty starred in 2002 British movie Bend It Like Beckham, and while her career took off after the film became a hit, some critics weren't so kind to the actress. But Knightley isn't bitter about her bad reviews, saying, "I completely agreed on every level."
