I have a huge list of movies (and a few TV shows) that don't seem to have made the jump. Some are great (the BBC series of Tinker, Tailor, Soldier, Spy and Smiley's People), some of them are very cult (Meet the Feebles), and some are just bad (Poor White Trash II, originally titled Scum of the Earth). Everyone said that streaming would make the "long tail" accessible because the costs to transfer and distribute would be so low, but that doesn't seem to have happened, at least to the extent that I'd like.
(I've had the same issue with music--my MP3 collection consists of a few dozen LPs that I've ripped because they were never digitized and added to the different services.)
