I can't agree on OP's criticism of They Will Not Grow Old. First, the used footage was not an art movie. It was journalistic/documentary. It was meant to show reality (although mostly as propaganda). Second, the restoration manages to bridge the gap between 1914 and 2014. Old B/W movies tend to give an impression of artificiality and distance. Seeing the colorized, interpolated version makes these soldiers people of blood and flesh. "This could happen to YOU", is what the movie says, and it couldn't have achieved it with the original footage. Given the slaughterhouse that was WWI, it seems entirely appropriate.
