Grimsby (MA15+) The burden of expectation on comedians is relentless, which is a concise way of saying Sacha Baron Cohen’s latest comedy is disappointing. The clear difference with Cohen’s previous films and characters is they were satirical; Grimsby is a parody, so it’s harder to forgive his misfires here because there is no substance behind them. It is a parody of a spy film meets buddy film in which Cohen plays Nobby, an English soccer lout with a Liam Gallagheresque haircut and chops. Unlike Cohen’s previous films, Grimsby is all excess and no subtlety. This is Cohen’s film and he delivers his share of healthy, guilty laughs — just not his usual share, or with his usual flair.
