Boyle and Garland have, in their dotage, outdone themselves. The first film was good, the second almost entirely forgettable, but this third act, wow, fucking fantastic. “28 Swinging Cocks”, “28 Inch Cock” or "28 Dicks Later", any could have been apt titles, but that’s too easy. This is the movie in which the anatomy is riotous, the intellect unashamed, the heart unexpectedly exposed.
