I own every film released so far in the Film Vault collection, and it makes the completist in me very happy indeed:
Fun fact - of these 10 "classic" films, there are 2 I've never seen. Ever. And these are not the only examples of films that I own on Blu-ray/4K that I've never seen and haven't got round to seeing yet. This is bad - I need to make time to watch these, even with all the other stuff I need (want) to watch.
