"... Kren's next important systematic film is TV (1967). In TV, the system is different in kind and pace from that which exists in much of his other work. Instead of operating primarily at the kinetic level, or with rapid perceptual rhythm, this film involves the audience in a conceptual and reflexive process. Five short sequences, each about eight frames long, are all shot from the same viewpoint in a quay-side cafe. They show a window, broken by the silhouettes of objects and people within the cafe and by the passage of people and a ship outside. Each shot containing some small movement is repeated in the film 21 times, in mathematically determined order. They are separated by short, equal sequences of black spacing, except that longer black sequences separate larger phrases of repeats from each other rather like punctuation. The significance does not lie in the mathematical sequences as such, but in how the viewer attempts to decipher the structure." - Malcolm Le Grice, Abstract Film and Beyond
