I wouldn't call some of the anime films you listen unseen though they are popular among certain circles. Though different circles than film fans frequent. In general 99% of the great movies are not watched by many people just the new Hollywood stuff gets high exposure and that's it, even movies like Fanny and Alexander are known only among film buffs and film critics, groups which are like 0.1% or less of the population of US or Europe.
Oh yeah, that's something I should clarify here; I am not merely talking about unseen there, but am applying an objective cut-off point. Basically anything 30 or more minutes length that has less than 500 votes in that website and I rated 8 or higher. Anime fans are underrepresented in the website, so it's natural that there are various movies there (however, a lot more people know about the
Madoka franchise (in this forum, thanks to your heated campaign
) than they know about the
Sekai Meisaku Dowa films. So even in that case there are levels). That's why I'd take my list with a grain of salt, and go in a case by case basis. There's unknown, but there's also partially known and even reasonably popular there whose fanbase for some reason is misrepresented.
Anyway, to give some context to these data,
Fanny and Alexander has >14,000 votes there at this moment (>36,000 at IMDb, but IMDb has a far wider spectrum).
Cool list, jal90. I've seen some films from it. I've seen some films that are not on the list and NOT EVEN IN THE WHOLE SITE DATABASE. HEHEHE. Now that's what I call obscure.
Check if they appear in IMDb. If they don't, they may be obscure enough for you
