Yes, one knows what one will be getting in a J. Statham movie, and he delivers every time. In a way he puts me in mind of Clifton Webb, who, after starring in Laura, he played the identical character in every role in film after that.
Granted Statham has played some good comedy roles, but he's almost always called upon to play a vengeful bad dude. Here, the story was pretty cookie cutter trite, although with a decent hook.
And I too am sick to death of the prurient and exaggerated use of foul language in film. It's become like fingernails scraping on a black board. Evidently producers and writers think that foul language makes films "hip". Good films don't need it.
