Thought I'd put things into perspective. I've downloaded Leonenut's Manhunter Extended Edition, and I see that the best quality source material wasn't used. Looks like he mainly utilized footage from the Restored Director's Cut, but as you see below, that is the worst of the three. Not only are the colors desaturated, but it's also the darkest transfer of all three. The desaturated colors seem to be an issue with the Anchor Bay Divimax releases (such as the Halloween Divimax DVD).
