It’s been either total disinterest, or ‘Oh, that MUST be worth something’, or a look that suggests pity and that you might be very immature or subnormal in some way, as a general rule.
Very occasionally I’ll meet someone who’s genuinely interested, but with nowhere near the intensity that I go about it.
Still, little point in mentioning or bothering to pull out the first Thanos or something else that there’s a degree of awareness about because of a film, for a transitory, nonchalant, ho-hum response.
I just keep my manic enthusiasm for our favourite medium to myself.
