Yeah, that's exactly what I'm talking about. People do that with Star Wars a lot as well. Always gives me second hand embarassment.
Plus like, leaving all else aside, I've never understood how peer pressure and making somebody feel lesser for not seeing a particular movie is supposed to make them enthusiastic about doing that (though of course much of the time that isn't the point, it's a mask for a smug sense of superiority)
I believe he was talking about the film from 1973, which Kill Bill heavily homages (or rips off, depending on how charitable you're feeling) but shit, I never knew Lady Snowblood was originally a manga.
