The subject of the film was very interesting but I became increasingly annoyed by the directors showing off. "I felt I was underwater' cut to footage shot underwater. 'I felt I was in a movie', cut to footage imitating a b movie, the director felt the need to underline everything as if the viewer could not imagine for themselves. Words were repeatedly scrawled over the image accompanied by an effect, OK for a while but it repeatedly became a stylistic tic. Tiresome. A shame because the subject was fascinating, It would have been better if the animations were in ironic counterpoint not simply illustrative. There were also many, many shots of telephones.
