I first saw Pasolini's Trilogy of Life in 1997. For the next few years it was only available on low quality video tapes and bootlegs, or $200 DVDs or similarly low quality. Since 2001 or so it hasn't been available at all, even bootlegs being hard to find. On many occasions I'd even considered buying these terrible versions at rare eBay prices. But a few days ago, Criterion gave it the full restored Blu-ray treatment, and it is spectacular:

Goes well with their Salo Blu-ray too.
